Anna Wintour
A Super First (We Think)

If there's anything still in dispute in fashion, it's who can lay claim to the title of first supermodel. Although she probably wasn't the first, Janice Dickinson isn't shy about taking credit. And we can't say we blame her. Dickinson's been on 37 Vogue covers, and although she turned 56 in 2011, she's reinvented herself as a television host and self-made business maven.

Since 1988, American Vogue editor Anna Wintour has steered not only the sensibilities of dear readers, but those of the industry as a whole. If Wintour puts tweed on the cover, the entire world seems to mimic the academia-turned-high-fashion look. Vogue -- whether Wintour's version or the more literal sense of the word -- has an undeniable place in nearly every woman's vocabulary. Now that's power.

The fiercely fashionable Wintour, who reportedly was the inspiration behind the movie "The Devil Wears Prada," may be known for snarkiness as much as impeccable taste. Still, when we pull an aubergine blouse off the rack in October because she featured the color in the publication's fall fashion issue, we'll tip our hats to Wintour -- if hats are "in" this season, that is.
