Stella McCartney — Luxury Without Leather

McCartney has never used leather or fur in her designs — since founding her label in 2001, well before sustainable fashion was fashionable. She built a genuinely successful luxury brand without animal products, pushing questions of supply-chain sustainability further into the mainstream conversation at LVMH, Kering, and Hermès. LVMH took a minority stake in 2019 and appointed her as a sustainability advisor across the group. Yes, she's Paul McCartney's daughter. But after 25 years of building a brand that changed how fashion talks about materials, that fact is the footnote, not the headline.
