David Arquette as Elvis and Michelle Trachtenberg had the creepy but brilliant costume of a child pageant star.
JWoww and Snooki booth made sure they were in something revealing, but props to Snooki for originality as a Pickle Princess.
Amanda Seyfried as a dog and Nicole Richie as Margot Tenenbaum at Kate Hudson's annual Halloween party.
