Since the age of 7, Dakota Fanning has had a strong presence on the red carpet, always dressed in charming, age-appropriate party dresses. Now 18, Fanning has developed a taste for modern, conceptual outfits from designers like Proenza Schouler, Rodarte, and Prada. A regular at Fashion Week, the actress isn't afraid to make runway looks her own, often going for the full, show-stopping effect — see the Valentino gown she chose for the 2011 Met Gala, for example, or the pink Lanvin number she wore to the Tribeca Film Festival.
