Amanda Seyfried's on-screen style may have ranged from Mean Girls preppy to Lovelace racy, but her style on the red carpet is as consistently pretty as her cascading flaxen hair and wide-set blue eyes make her in person. 

Often seen in Givenchy, for whom she is the current face, she's also known to have a penchant for Prabal Gurung and Valentino, as well as looking to Alexander McQueen when she really wants to step the drama up a notch.
