Cool, principled, and approachable, Stella McCartney is adored by women everywhere because they identify with her as a working wife and mother as much as they like wearing her designs. McCartney has redefined what it means to have your own label backed by a luxury conglomerate—in this case, Kering, many of whose other brands produce leather goods—as she maintains her rigorous and absolute commitment to her ethical principles. She has managed to create vegetarian leather accessories, which have struck a real chord. Her recent collections have played with outsize proportions, twisted elegance for evening, and denim, both dressed up and dressed down. Yet the thread that unites them all is the idea that her designs should be easy to wear, regardless of your age.
