Renowned fashion designer Mossimo Giannulli has an estimated net worth of $50 million in 2012. He is best associated with the Mossimo fashion house which he founded in Balboa Island in Newport Beach, California in 1968. The company is known for its impressive creations and collections of accessories, jeans, jackets, and t-shirts which are especially made for teens.

On the company's first year, Mossimo Giannulli earned $1 million. In 1996, the company earned $76 million annually with a profit of $12 million. Eventually, the brand expanded into other market segments by manufacturing garments for men and women of older ages.

A year later, the company lost $19 million. As the company continues to incur losses, Mossimo eventually sold to Iconix Brand Group. The company's products are now solely sold at Target.

Currently living in Bel Air California, Mossimo Giannulli is married to Lori Loughlin with whom he has two daughters.
