Dakota Fanning

If the name Dakota Fanning conjures up images of a wide-eyed child star with blond braids and Mary Janes, it's time to think again. After years of children's fare, 16-year old Fanning recently starred as punk rocker Cherie Currie in The Runaways, a biopic of rock star-proportions with cover girl Kristen Stewart playing Joan Jett. Fanning has channeled her new mature role on the red carpet with lots of black, like this stunning Valentino lace mini (paired with soaring burgundy heels) and the chic black blazer-and-skinny pants combo she wore at Sundance. Savvy style is matched by smart career moves: Fanning's next film is none other than the next film in the Twilight series, Eclipse.
