The classic bob has been modernized by many generations of women, most recently by Vogue ice queen Anna Wintour, but it dates back to the Roaring '20s and one of the original American flappers, Zelda Fitzgerald. The wife of author F. Scott Fitzgerald, Zelda didn't let her tempestuous marriage stop her from becoming an in-demand socialite and an icon of the jazz age. Wearing her soft curls in a short, chin-length style, she epitomized a life of glamour and rebellion. And the bob, which had been a practical style during World War I, became a hallmark of women's independence in the flapper era.
