The fabulous life of Renzo Rosso, the 'crazy' billionaire founder of one of the most iconic denim brands in the world

Diesel founder Renzo Rosso has built a clothing empire.

The "hard-partying, trash-talking billionaire bad boy," as W Magazine called him, went from son of a northern Italian farmer to amassing a small fortune. He refers to himself as "crazy" for his outsized creativity and vision, according to Women's Wear Daily.

He first appeared on the Forbes billionaires list in 2012, and he currently has a net worth of roughly $3.4 billion, which he acquired through provocative advertising, savvy retail acumen, and smart business sense.

Though he's since relinquished the reigns of the company he created, the 60-year-old still serves as president of its holding company, OTB (which stands for Only The Brave, a company motto), and it doesn't seem like he'll slow down any time soon.

Rosso sat down with Business Insider to give us a small peek into what his fabulous life is really like.
