Twiggy turns 63 today! Born in England as Lesley Lawson, the model first broke onto the fashion scene in the über-mod 1960s, eventually earning her name due to both her thin build and her childhood nickname, "Twigs." Certainly ahead of the curve, she glamorized a daringly short pixie cut and generally androgynous appearance, both of which inspired major trends adopted by modern-day celebrities—from Pink to Rihanna to Miley Cyrus. We're celebrating Twiggy's contributions today, not only to fashion and beauty (check out her successful HSN line), but also to strong women everywhere. Happy birthday!
