Renzo Rosso

Renzo Rosso transformed premium denim into a global lifestyle statement, building OTB into a €1.6 billion fashion conglomerate. By radically reshaping Diesel's branding in the 1990s, he made ripped and distressed jeans a luxury commodity, driving margins 40% higher than the average denim producer. Rosso's Marni and Maison Margiela acquisitions under OTB outperform #6 Miuccia Prada's standalone ready-to-wear margins by 12%, proving his group's synergy model outruns family-run houses.
