Mossimo Giannulli Net Worth: How the Fashion Designer Built a $40 Million Fortune

Mossimo Giannulli Net Worth: $40 Million

Mossimo Giannulli is an American fashion designer and entrepreneur best known for creating the Mossimo clothing brand, one of the most recognizable youth-fashion labels of the 1990s. What began as a small surfwear business on Balboa Island grew into a multimillion-dollar fashion empire, eventually becoming a publicly traded company and reaching a point where Giannulli’s personal stake was valued at approximately $500 million on paper.

Giannulli’s financial story is far more complicated than a simple rise-to-riches tale. He built Mossimo from a $100,000 family loan, transformed it into a major fashion company, watched the value of his stake plunge by hundreds of millions of dollars, and eventually rescued the brand through a licensing partnership with Target. The brand was later sold to Iconix Brand Group in 2006.

His personal life has also attracted enormous public attention. He was married to Full House actress Lori Loughlin for nearly three decades, and the couple became embroiled in the 2019 college admissions scandal known as Operation Varsity Blues. Both eventually pleaded guilty and served federal prison sentences.

In 2025, Giannulli and Loughlin separated after nearly 28 years of marriage. In September 2026, Loughlin formally filed for divorce, citing irreconcilable differences. Court documents indicate that the couple had a prenuptial agreement that was amended in 2015.

So, how did Mossimo Giannulli make his money, how did his $500 million paper fortune disappear, and what is his financial situation today? Here’s a detailed look at his career, business empire, investments, real estate, family, legal troubles, and net worth.

Who Is Mossimo Giannulli?

Mossimo Giannulli is a Los Angeles-born fashion entrepreneur who became famous for building the Mossimo lifestyle and clothing brand.

Unlike many celebrity entrepreneurs who build businesses after becoming famous, Giannulli’s fame largely came from his business success. He was already a wealthy and influential fashion executive before his marriage to Lori Loughlin made him a familiar name in entertainment circles.

The Mossimo brand became particularly popular among younger consumers during the late 1980s and 1990s. Its surf-inspired aesthetic, recognizable logo and relatively accessible prices helped turn it into a major youth-fashion label.

Giannulli’s business career demonstrates both sides of entrepreneurial success.

At one point, his 73% ownership stake in Mossimo was worth approximately $500 million on paper. But the company’s attempt to move into higher-end fashion caused its stock to collapse, reducing the value of his stake to around $50 million.

Rather than allowing the business to disappear, Giannulli changed strategy. His licensing agreement with Target transformed Mossimo into a mass-market brand and ultimately helped preserve the value of the company.

That ability to recover from a massive financial setback became one of the most important chapters of his business career.

Early Life and Background

Mossimo Giannulli was born on June 4, 1963, in Los Angeles, California, and grew up in the Encino area.

Interestingly, his original birth name was spelled Massimo. According to accounts of his childhood, he changed the spelling and pronunciation to “Mossimo” when he was in first grade after a teacher suggested the original pronunciation might be difficult for classmates.

Growing up in Los Angeles gave Giannulli an environment where fashion, entertainment, youth culture and entrepreneurship were constantly visible.

After graduating from high school, he attended the University of Southern California.

However, Giannulli did not follow the traditional route of completing a university degree and entering a conventional career. He eventually left USC because he was more interested in pursuing business.

That decision became a defining moment.

Instead of spending years preparing for a corporate career, Giannulli decided to build his own company.

His first major business would ultimately become one of the most recognizable clothing brands in America.

How Mossimo Giannulli Started His Fashion Business

In 1986, Giannulli borrowed approximately $100,000 from his father to start a clothing company.

The business was launched from a garage on Balboa Island in Newport Beach, California.

At the time, Giannulli was not trying to create a huge international fashion corporation. His initial concept was much simpler.

He wanted to create stylish clothing influenced by the Southern California beach lifestyle.

The first products included:

• T-shirts
• Volleyball shorts
• Surfwear
• Casual apparel
• Beach-inspired clothing

The company adopted a distinctive stylized “M” logo that eventually became closely associated with the Mossimo name.

Giannulli focused on young consumers who wanted fashionable clothing but did not necessarily want to pay luxury-fashion prices.

That positioning proved extremely effective.

The Early Success of Mossimo

Mossimo’s growth was surprisingly fast.

The company reportedly generated around $1 million in revenue during its first year.

By its second year, revenue had climbed to approximately $4 million.

For a business that had started in a garage with a $100,000 loan, those numbers were extraordinary.

Giannulli understood that Mossimo was not simply selling clothes. It was selling a lifestyle.

The brand represented the relaxed California image associated with surfing, beaches, youth culture and Southern California fashion.

That image helped the company stand apart from traditional clothing manufacturers.

Giannulli continued expanding the product range beyond simple surfwear.

Mossimo began producing:

• Sweaters
• Sweatshirts
• Knits
• Women’s clothing
• Men’s apparel
• Accessories
• Tailored clothing

By 1992, Mossimo was generating approximately $32 million in annual revenue.

The company was no longer a small local clothing operation.

It had become a serious fashion business.

Mossimo Becomes a Major Youth-Fashion Brand

The 1990s were a particularly important period for American youth fashion.

Surfwear and streetwear were becoming increasingly influential. Brands associated with Southern California culture were gaining national attention.

Giannulli positioned Mossimo directly in that growing market.

The company’s appeal came from a combination of branding, accessibility and youth-oriented design.

Mossimo products eventually became available through approximately 1,700 stores across the United States, along with hundreds of international retail locations.

The scale of distribution was a major achievement.

For Giannulli, this meant that the company had evolved from a small apparel business into a recognizable national brand.

Revenue also continued climbing.

By the middle of the 1990s, Mossimo had become valuable enough to enter the public markets.

The 1996 Mossimo IPO

One of the biggest milestones in Giannulli’s career came in 1996, when Mossimo went public.

At the time, the company was generating approximately:

• $76 million in annual revenue
• $12 million in annual profit

Giannulli retained approximately 73% ownership of the company.

Following the initial public offering, his stake was worth approximately $275 million on paper before taxes.

That made Giannulli one of the youngest and wealthiest entrepreneurs in the fashion business.

He was only 32 years old.

The success was remarkable considering that the company had started just a decade earlier with a $100,000 loan.

But the biggest financial numbers were still ahead.

How Mossimo Giannulli’s Fortune Reached $500 Million

Following the IPO, Mossimo’s stock price continued to rise.

At the height of the company’s stock-market success, shares traded at approximately $50 each.

Because Giannulli still controlled around 73% of the company, the value of his ownership stake reached an estimated $500 million.

This is an important distinction when discussing Mossimo Giannulli’s net worth.

The $500 million figure represented the paper value of his ownership stake, not necessarily $500 million sitting in a bank account.

Stock prices can rise and fall dramatically.

If Giannulli had sold his entire position at the absolute peak, he could potentially have converted much of that paper wealth into cash, subject to taxes, market conditions and transaction factors.

Instead, he remained heavily exposed to the company’s future.

And the company’s future soon became much less certain.

The Fashion Expansion That Went Wrong

After becoming extremely successful with surfwear and youth clothing, Giannulli decided to expand Mossimo into higher-end fashion.

On paper, the strategy made sense.

The company had a powerful brand, strong sales and a large customer base.

Moving into more expensive apparel could potentially increase profit margins and establish Mossimo as a broader fashion house.

But the strategy created a serious problem.

Mossimo began moving away from the market that had originally made it successful.

The company spent more money developing and producing its new products, while its traditional customers became less enthusiastic about the brand’s changing identity.

At the same time, Mossimo struggled to attract enough upscale consumers to replace the lost momentum.

The result was a dramatic decline in the company’s financial performance.

From a $500 Million Stake to Around $50 Million

Mossimo’s stock price collapsed.

By 1998, shares had fallen approximately 90% from their peak, dropping to roughly $4.75.

Giannulli’s stake, which had previously been worth approximately $500 million, fell to around $50 million on paper.

That represented a staggering decline in personal paper wealth.

In a relatively short period, an entrepreneur who had appeared to be worth hundreds of millions of dollars had watched most of the value of his publicly traded stake disappear.

This period became one of the most important lessons in Giannulli’s business career.

The brand was not necessarily dead.

But the strategy had failed.

Giannulli needed to find a new way to make Mossimo profitable.

The Target Deal Changed Everything

Instead of continuing to pursue high-end fashion, Giannulli eventually adopted a completely different strategy.

In 2000, Mossimo entered into a major licensing agreement with Target.

The deal was transformational.

Rather than Mossimo having to carry the full burden of manufacturing, distribution and retail operations, the brand could license its name and designs to Target.

Target could then manufacture and distribute Mossimo products through its enormous retail network.

This created several advantages for Giannulli.

Lower Operating Costs

Mossimo did not have to maintain the same enormous operational infrastructure required by a traditional apparel company.

Wider Distribution

Target gave Mossimo access to millions of customers across the United States.

Royalty Income

Giannulli could earn money from the brand through licensing rather than relying entirely on direct clothing sales.

Brand Revival

The agreement allowed Mossimo to return to the accessible, mass-market fashion territory where the brand had originally been successful.

According to the information provided, the initial Target arrangement reportedly generated approximately $8.5 million per year in royalties for three years.

The licensing strategy helped stabilize the Mossimo brand.

It was a significant turnaround.

The Sale of Mossimo in 2006

Giannulli eventually sold Mossimo to Iconix Brand Group in 2006.

The transaction was valued at approximately $135 million, including cash and assumed debt.

The sale marked the end of Giannulli’s direct control over the company he had founded two decades earlier.

The journey had been extraordinary.

He started with:

$100,000

He built a company generating tens of millions of dollars in annual revenue.

He took the company public.

His stake briefly reached approximately:

$500 million

The company then collapsed in value.

His stake dropped to approximately:

$50 million

He subsequently rebuilt the business through licensing.

And finally, the brand was sold for approximately:

$135 million

This long business cycle is one of the biggest reasons Mossimo Giannulli remains an interesting figure in the fashion industry.

Mossimo Giannulli’s Sources of Wealth

Although the Mossimo clothing brand is by far the most important source of Giannulli’s fortune, his wealth has been associated with several different areas.

1. Mossimo Clothing Brand

The foundation of Giannulli’s fortune was Mossimo.

He founded the company, controlled a large percentage of its stock after the IPO and benefited from the company’s eventual licensing and sale.

2. Licensing Revenue

The Target agreement provided a significant source of income through royalties.

Licensing can be particularly attractive for fashion entrepreneurs because it allows a brand owner to generate revenue without necessarily handling every stage of production and retail.

3. Company Sale

The 2006 sale of Mossimo to Iconix Brand Group provided another major financial event in Giannulli’s career.

4. Real Estate

Giannulli and Lori Loughlin accumulated a substantial real estate portfolio during their marriage.

Their properties included luxury homes in Bel Air, Beverly Hills, Hidden Hills, Aspen, Laguna Beach and La Quinta.

5. Investments and Other Assets

Like many wealthy entrepreneurs, Giannulli’s overall net worth is not simply a reflection of his original business.

His financial position has also been influenced by property transactions, investments, taxes, legal costs and other personal expenses.

Mossimo Giannulli and Lori Loughlin

Giannulli’s personal life became highly public because of his relationship with actress Lori Loughlin, best known for playing Aunt Becky on Full House.

The pair reportedly met in 1995 while Loughlin was still married to investment banker Michael R. Burns.

Loughlin’s divorce was finalized in 1996.

She and Giannulli married in 1997.

Their marriage lasted nearly three decades.

Together they had two daughters:

• Isabella Rose Giannulli
• Olivia Jade Giannulli

Giannulli also has a son, Gianni, from a previous relationship.

For many years, Giannulli and Loughlin were regarded as one of Hollywood’s wealthier couples.

Their combined finances allowed them to buy and sell several luxury properties across California and other desirable locations.

However, their marriage would eventually become closely associated with a major national scandal.

The Operation Varsity Blues Scandal

In 2019, Mossimo Giannulli and Lori Loughlin became two of the most prominent names connected to the nationwide college admissions scandal known as Operation Varsity Blues.

Federal prosecutors alleged that wealthy parents had paid money to admissions consultant Rick Singer’s organization to manipulate the college admissions process.

In the case involving Giannulli and Loughlin, prosecutors alleged that approximately $500,000 was paid to have their daughters presented as athletic recruits for admission to the University of Southern California.

The case received enormous media attention.

The couple initially pleaded not guilty and fought the charges for more than a year.

Eventually, both accepted plea agreements.

Mossimo Giannulli’s Prison Sentence

In May 2020, Giannulli agreed to plead guilty to a federal conspiracy charge.

He was sentenced to:

• Five months in federal prison
• $250,000 fine
• 250 hours of community service
• Two years of supervised release

Giannulli reported to federal prison on November 19, 2020.

He was later transferred to home confinement and was released in April 2021, after serving a little more than four months.

The legal case represented a dramatic change in his public image.

Before the scandal, Giannulli was primarily known as a successful fashion entrepreneur and the husband of a famous television actress.

Afterward, his name became permanently connected to one of the most publicized college-admissions cases in American history.

How the Scandal Affected His Finances

It is difficult to calculate exactly how much money Giannulli lost because of the scandal.

However, the financial consequences were substantial.

The family faced:

• Legal fees
• Criminal fines
• Lost professional opportunities
• Property transactions
• Public-relations consequences
• Significant disruption to their personal lives

Giannulli’s $250,000 criminal fine was only one direct financial penalty.

The broader costs of a federal criminal case can be considerably higher when attorneys, consultants and other expenses are included.

Nevertheless, the scandal did not eliminate Giannulli’s wealth.

His previous success in fashion and accumulated assets left him with substantial financial resources.

Mossimo Giannulli’s Luxury Real Estate Portfolio

Real estate has been another important component of Giannulli’s financial history.

During his marriage to Loughlin, the couple bought, renovated and sold numerous luxury homes.

Their property transactions show just how substantial their combined wealth became.

Bel Air Mansion

One of the couple’s most notable properties was a mansion overlooking the Bel-Air Country Club.

They purchased the property in 2015 for approximately $14 million.

The couple spent millions renovating and upgrading the home.

Eventually, they placed the property on the market for approximately $35 million.

That price proved difficult to achieve.

The asking price was later reduced to approximately $28.7 million.

The property eventually sold in 2020 for around $18 million.

The buyer was Tinder co-founder Justin Mateen.

The sale became especially notable because it happened shortly after Giannulli and Loughlin resigned from the Bel-Air Country Club amid controversy surrounding their criminal case.

Beverly Hills Property

Before their Bel Air property, Giannulli and Loughlin owned a large Beverly Hills mansion.

They sold the home in 2015 for approximately $18 million.

The transaction was another example of the couple’s ability to buy, renovate and sell high-value properties in Southern California.

Their real estate activities were not necessarily simple investments.

Luxury homes also served as primary residences and reflected their lifestyle during the height of their wealth.

Aspen Home

Giannulli and Loughlin also owned a luxury property in Aspen, Colorado.

They sold the home in July 2015 for approximately $7.6 million.

Aspen has long been one of the most expensive resort markets in the United States, making the property consistent with the couple’s broader real estate portfolio.

Laguna Beach Property

One of the couple’s longest-held properties was located in the exclusive Emerald Bay community in Laguna Beach.

They acquired the home in 1997 for approximately $1.36 million.

More than a decade later, they attempted to sell it for approximately $12.99 million.

But the timing proved unfortunate.

The housing market suffered a major collapse, forcing them to reduce the asking price to around $8.5 million.

They eventually sold the property for approximately $4.1 million.

The transaction illustrates another important aspect of Giannulli’s wealth story: owning expensive real estate does not automatically guarantee a profit.

Market conditions, renovations, taxes, commissions and timing can dramatically affect the final result.

Hidden Hills Mansion

Following the 2020 college admissions scandal and prison sentences, Giannulli and Loughlin eventually established a new home in Hidden Hills, California.

In August 2020, they paid approximately $9.5 million for a newly built mansion.

The approximately 12,000-square-foot property reportedly included:

• Six bedrooms
• Nine bathrooms
• Swimming pool
• Home gym
• Movie theater
• Wine cellar
• Large outdoor entertaining areas
• Approximately 1.6 acres of land

The property was a major luxury purchase during a period when the couple was dealing with enormous legal and public scrutiny.

In April 2024, the home was listed for approximately $17.5 million.

It remained on the market for more than a year.

The couple ultimately sold it for approximately $12.65 million in October 2025.

The sale occurred around the same period that their separation became public.

The Madison Club Property

Giannulli and Loughlin also invested heavily in the luxury community known as The Madison Club in La Quinta, California.

In September 2021, they paid approximately $13 million for a roughly 9,000-square-foot home.

The Madison Club is known for its exclusive membership and luxury properties.

The couple eventually sold the home off-market in late 2025 for approximately $16.5 million.

That represents a gross increase of around $3.5 million over the purchase price.

However, gross appreciation is not the same as net profit.

Renovation costs, property taxes, maintenance, commissions and other expenses can substantially reduce the amount an owner ultimately keeps.

Mossimo Giannulli Net Worth in 2026

As of the September 8, 2026 estimate provided by Celebrity Net Worth, Mossimo Giannulli has an estimated net worth of $40 million.

That figure is dramatically lower than the approximately $500 million paper value of his Mossimo stake at its peak.

But the comparison needs context.

The $500 million figure represented the value of a publicly traded ownership stake during a period when the company’s stock was extremely high.

It was not necessarily cash available to Giannulli.

Stock prices fluctuate.

Taxes affect realized wealth.

Business expenses, legal costs, property transactions and personal spending can all reduce net worth.

His current estimated fortune therefore reflects a much broader picture of his financial history.

Why Is Mossimo Giannulli Worth $40 Million Instead of $500 Million?

This is probably the biggest question surrounding Giannulli’s wealth.

The answer involves several factors.

1. Mossimo’s Stock Collapse

The biggest factor was the collapse of Mossimo’s stock after the company’s expansion into higher-end fashion failed.

His stake reportedly declined from approximately $500 million to around $50 million on paper.

2. Taxes

Large business transactions and stock sales can generate significant tax obligations.

3. Luxury Real Estate

Giannulli and Loughlin spent substantial amounts on multimillion-dollar properties, renovations and maintenance.

4. Legal Expenses

The college admissions case generated substantial legal costs.

5. Criminal Fine

Giannulli was ordered to pay a $250,000 fine as part of his sentence.

6. Lifestyle Expenses

Maintaining multiple luxury homes, private travel, staff, cars and other high-end expenses can require significant ongoing income.

7. Changes in Business Ownership

Giannulli no longer controls Mossimo in the same way he did when he founded the company.

The brand was sold to Iconix Brand Group in 2006.

Together, these factors explain why the entrepreneur’s current estimated net worth is far below his historical peak.

Mossimo Giannulli’s Divorce From Lori Loughlin

Giannulli’s financial situation has gained renewed attention in September 2026 because of his divorce from Lori Loughlin.

The couple separated in 2025 after nearly 28 years of marriage.

Loughlin’s representative confirmed at the time that they were living separately and taking a break from their marriage.

In September 2026, Loughlin formally filed for divorce.

According to court documents reported by ABC News and other outlets, she filed in Los Angeles Superior Court on September 4, 2026, citing irreconcilable differences. The filing lists August 31, 2025 as the separation date.

The couple reportedly signed a prenuptial agreement before their 1997 marriage and amended it in 2015.

Loughlin’s filing asks that their property, assets and liabilities be handled according to the terms of that agreement. Spousal support remains a separate issue to be determined.

Because their children are adults, custody and child-support arrangements are not part of the divorce.

Will the Divorce Change Mossimo Giannulli’s Net Worth?

It is too early to know exactly how the divorce will affect Giannulli’s personal fortune.

The existence of a prenuptial agreement could be significant because it may establish how separate and community property are treated.

However, the precise terms of the agreement have not been publicly disclosed.

The former couple had already sold several major properties around the period of their separation.

That includes:

• Hidden Hills mansion — approximately $12.65 million sale
• Madison Club property — approximately $16.5 million sale

The final financial consequences of the divorce will depend on the classification of assets, the terms of the prenup, liabilities and any eventual agreements or court orders.

Therefore, it would be premature to claim that Giannulli’s $40 million estimate will definitely increase or decrease because of the divorce.

Mossimo Giannulli and His Children

Giannulli and Loughlin have two daughters together:

Isabella Rose Giannulli

and

Olivia Jade Giannulli

Olivia Jade became particularly well known as a social-media influencer and creator.

She built her own online following through lifestyle, beauty and fashion-related content.

Both daughters were at the center of the media attention surrounding the college admissions scandal, although the criminal case was prosecuted against their parents.

Giannulli also has a son, Gianni, from a previous relationship.

The Mossimo Brand’s Cultural Legacy

Although Giannulli’s public image has changed considerably over the years, the Mossimo brand remains an important part of the history of American youth fashion.

The company’s success helped demonstrate the commercial potential of surf-inspired clothing.

Giannulli understood something that many traditional fashion companies struggled with at the time:

young consumers wanted brands that represented an identity, not merely clothing.

Mossimo sold a California lifestyle.

Its success also demonstrated the power of turning a local aesthetic into a national consumer brand.

The eventual Target licensing deal further demonstrated how a fashion label could transition from an independent designer brand into a mass-market retail identity.

The Biggest Lessons From Giannulli’s Business Career

Mossimo Giannulli’s financial journey contains several valuable business lessons.

Start Small

Mossimo began with a relatively modest $100,000 loan.

Giannulli did not need billions of dollars to build his first company.

He started with a simple product and a clear target customer.

Build a Strong Brand

The Mossimo logo and California lifestyle became more valuable than individual pieces of clothing.

That brand recognition helped the company survive major strategic mistakes.

Don’t Abandon Your Core Customer

One of Giannulli’s biggest business mistakes was attempting to move Mossimo too far into high-end fashion.

The company’s original customers were young, casual-fashion consumers.

Moving away from that audience damaged the brand.

Adapt When a Strategy Fails

Giannulli did not continue indefinitely with a failing strategy.

The Target licensing agreement represented a major strategic change.

Instead of trying to operate Mossimo as an expensive independent fashion house, he used licensing and mass retail to rebuild the brand.

Paper Wealth Isn’t Cash

Perhaps the most important financial lesson is the difference between net worth and liquid wealth.

Giannulli’s stake reached an estimated $500 million at its peak.

But when the stock collapsed, so did the value of that stake.

An asset valued at hundreds of millions of dollars can lose much of its value if the underlying company struggles.

Mossimo Giannulli Net Worth Compared With His Peak Fortune

The contrast between Giannulli’s current estimated wealth and his peak paper fortune is striking.

Period	Approximate Wealth/Value
Initial business funding	$100,000
Mossimo first-year revenue	~$1 million
Mossimo second-year revenue	~$4 million
1992 company revenue	~$32 million
1996 company revenue	~$76 million
1996 company profits	~$12 million
Post-IPO Giannulli stake	~$275 million
Peak estimated stake	~$500 million
Post-stock-collapse stake	~$50 million
2006 Mossimo transaction	~$135 million
2026 estimated net worth	$40 million

These numbers illustrate how dramatically entrepreneurial wealth can change over time.

Giannulli went from borrowing $100,000 to becoming associated with a $500 million paper fortune.

He later watched much of that wealth disappear and eventually built a still-substantial fortune estimated at $40 million.

What Does Mossimo Giannulli Do Now?

Giannulli has kept a relatively low public profile compared with the height of the Mossimo brand’s popularity.

His public identity today is closely tied to three major chapters of his life:

1. Fashion entrepreneur
2. Former husband of Lori Loughlin
3. Figure in the Operation Varsity Blues scandal

Unlike during Mossimo’s stock-market years, he is no longer running a major publicly traded fashion company.

His current financial position is therefore more connected to accumulated wealth, assets and investments than to an active fashion empire under his direct control.

Conclusion

Mossimo Giannulli’s story is one of the more dramatic wealth journeys in the fashion industry.

He started with a $100,000 loan from his father and transformed a small Balboa Island surfwear operation into a nationally recognized fashion brand.

Within a decade, Mossimo had become a major clothing company generating tens of millions of dollars in revenue.

When the company went public in 1996, Giannulli owned approximately 73% of the business, and the value of his stake eventually reached an estimated $500 million.

But his attempt to move into higher-end fashion caused the company’s stock to collapse.

His stake eventually fell to approximately $50 million.

Instead of abandoning the brand, Giannulli reinvented the business through the Target licensing agreement. The strategy restored Mossimo’s commercial relevance and ultimately preceded the brand’s sale to Iconix Brand Group in 2006.

His later life became dominated by events outside the fashion world, particularly his marriage to Lori Loughlin and their involvement in the college admissions scandal.

The couple eventually separated in 2025, and Loughlin filed for divorce in September 2026 after nearly 30 years of marriage. Their prenup and the division of their assets will be important factors in determining their final financial arrangements. (Good Morning America)

Today, Giannulli’s estimated $40 million net worth is a fraction of his historical $500 million paper fortune, but it still represents substantial financial success.

His career ultimately demonstrates that wealth can be created, lost, rebuilt and reshaped many times throughout an entrepreneur’s life.

From a garage on Balboa Island to a publicly traded fashion company, from a $500 million paper fortune to a major financial collapse, and from Target licensing to luxury real estate, Mossimo Giannulli’s financial story remains one of the most unusual in American fashion.
