2. Coco Chanel

In the 1920s, the eternally controversial Coco Chanel turned women's fashion on its head. Women from France to America began wearing their hair in bobs, adopting shorter skirts, and donning perfume. Over here in Britain we were a little appalled at her ideas surrounding androgynous style. That didn't stop the British Royal Family from cavorting with Chanel though, until she was accused of being a Nazi agent. Highly questionable political affiliations aside, Chanel was the queen of costume jewelry, which is still widely adored today.
