Stella McCartney — Luxury Without Leather

McCartney has never used leather or fur in her designs — since 2001, before sustainable fashion was fashionable. She proved a luxury brand could thrive at $1.5 billion+ revenue without animal products, forcing LVMH, Kering, and Hermès to rethink their supply chains. LVMH took a minority stake in 2019 and hired her as a sustainability advisor. Yes, she's Paul McCartney's daughter. But after 25 years of building a brand that literally changed how fashion thinks about materials, that fact is the footnote, not the headline.
