Although she's barely in high school, actress Elle Fanning has already won accolades for her fashion sense. She's appeared in magazines like Love, W, Vogue, and V, as well as a Marc by Marc Jacobs ad campaign. On red carpets, she takes advantage of her diminutive figure with voluminous skirts, baby-doll silhouettes, and girlish ruffles, and her loyalty to brands like Rodarte and Chanel have won her front-row seats at their fashion shows. Despite her young age, she manages to stay on the right side of appropriate with conservative cuts and high necklines. See her evolution from adorable tot to glamorous teen in our slideshow.
