For the Academy Awards red carpet, Amanda Seyfried chose an embellished gown with a sexy halter keyhole neckline by Alexander McQueen. For the Vanity Fair after party, the Les Miserables star decided to spice things up with a vibrant red gown by Givenchy that was cinched with a chic leather belt.
Both looks were gorgeous, but only one can emerge victorious in this Oscar fashion face-off. Check out more photos of Amanda Seyfried's Oscar night dresses below, then cast your vote!
