Rewind a generation for Brigitte Bardot's tousled hair, pouty mouth and sensual allure. Then fast-forward -- and surprise! -- blond tendrils again, lips in a pout and more curves than a scenic railroad. It's CLAUDIA SCHIFFER, the newest top star on the international fashion runway. Discovered in a Dusseldorf disco, Schiffer, 19, is being called the face of the '90s. She has already been on the cover of Vogue and Elle and showed off Chanel's latest collection. In her provocative ads for Guess?, Schiffer fills a pair of jeans in a way that cowboys only dream of.
