We’ve covered some of these already, like Karlie Kloss, Scarlett Johansson, and Alicia Vikander. But as usual, lots of ladies made a quick change in the limo/bathroom/meat locker between the telecast and the Vanity Fair Oscar party. It’s a very handy way to hedge your bets if you’re deciding between dresses — Rachel McAdams won best-dressed at the post-parties in a year she was a nominee, in part because liked that dress so much more than her first one — but it’s also a good way to have your cake and eat it, too. I’m serious. The second outfit should leave more room for cake.
