The Elton John AIDS Foundation Oscars Party is an annual fundraiser in disguise as one of the most high-profile soirees of the year. We caught up with our favorite stars at the party and asked them what iconic Oscar gown they'd like to take for a little spin. From Halle Berry's Elie Saab gown in 2002 to Julia Roberts' Valentino in 2001 and Angelina Jolie's Atelier Versace last year, today's fashionistas take a look back. See which Oscar dress Kim Kardashian, Miley Cyrus, Kelly Osbourne--and others--rank as their fave! Do you agree with the stars' picks? Tell us which are your favorite gowns in the comments!
