It's not easy emerging from the shadow of a Beatle father, but Stella McCartney has become a major force in fashion in her own right. Her signature jumpsuits and tuxedo pantsuits embody her design philosophy, combining minimalist tailoring with femininity and sophistication with ease of wear. Her love of functionality and clean lines has led to her branching off into sportswear, designing a line for Adidas and dressing Team GB for the London Olympics. A vegetarian like her parents, she refuses to use fur or leather, making her a favorite with similarly minded fashionistas. There's another boutique in South Kensington.
