In Italy, Gianni Versace, with his brilliant, sexy, and colorful designs, and Dolce & Gabbana, with their superfeminine and fantastical style, broke away from the serious and sober-minded fashions that dominated during much of the 1990s. The British designer Vivienne Westwood produced many influential and popular collections in the early 1990s, which included outfits inspired by 18th-century courtesans and the Marquis de Sade, with rounded hips, corsets, and platform heels. The London-based designer Rifat Ozbek was also popular, particularly in New York and Milan. His youthful style, which mixed references to India, Africa, and his native Turkey with clever takes on historical clothing, was reminiscent of hippest nightclubs and the more outrageous street fashions of the time. Rap music was a prominent influence on popular and street fashion during the early and mid-1990s. Followers of hip hop adopted huge baggy jeans, similar to those worn in American prisons, with big patterned shirts and heavy black shoes. The sports label Nike had great popularity and materials such as Lycra/spandex were increasingly used for sportswear. Increasing eco-awareness and animal rights made even top couture houses such as Chanel introduce fake fur and natural fibers into their collections.
