It was the decade of fashion when models became international celebrities. And the theme for fashion was that it was for everyone, not just the rich and famous. As Mary Qant, the British boutique owner and fashion designer said, "We wanted to increase the availability of fun for everyone. We felt that expensive things were almost immoral and the New Look was totally irrelevant to us." (Reed, loc. 714) And the center of the fashion world was not Paris, Rome or New York. It was swinging London, home of the Beatles and everything "fab".
