Just as the '60s were revolutionary in youth culture, the time redefined fashion. "Once only the rich, the Establishment, set the fashion. Now it is the inexpensive little dress seen on the girls in High Street," British designer and boutique owner Mary Quant has said of the transition. London's mod scene and American hippies began setting trends: dressing for self-expression, blurring traditional lines of gender identity, embracing sexuality and different silhouettes and materials. "The world is all for youth now," model Twiggy noted in 1967. "Because the young people have so much time and money to spend, all the businessmen say let's cash in on youth." Brands and boutiques boomed. Youthquake! explores that time through garments, accessories and video.
