When Ashley Greene first graced the pages of Marie Claire in March 2010 — styled exclusively in sexy Dolce & Gabbana — she was just a blip on fashion's radar. Now the Twilight star is the face of DKNY and a front-row regular. With a love of timeless classics (like the studded Chloé "Susan" ankle boots she wore to the L.A. set of our photo shoot), the 25-year-old has seized the style spotlight. For her second MC appearance—this time on the cover—Greene reveled in porcelain prints by Roberto Cavalli, chambray by Chanel, and the graphic manipulations of 3.1 Phillip Lim and Balmain. Of her Breaking Dawn costar Kristen Stewart's affair — the news of which had broken two days earlier — she remained mum. For Greene, there's no room for scandal when serious style is at hand. — Katie L. Connor
