According to her boss, PPR CEO François-Henri Pinault, fashion designer and Beatle progeny Stella McCartney is the new face of responsible luxury. "Stella has set the bar," he told Britain's Sunday Times. Across the pond, the Natural Resources Defense Council honored her this spring for her "outstanding environmental leadership." McCartney, 38, a PETA pet, uses no leather or fur; her skin-care line and ready-to-wear collection are both organic. Lest this sound too hair shirt to be stylish, consider Women's Wear Daily's review of the designer's latest fall collection: "McCartney's biker jacket in 'nonleather sheen cupro' can vroom with the best of them, and her thigh-high boots, in silk knits and perforated faux, strut the killer instinct she can live with." -- by Linda Tischler
