Rooney Mara in Givenchy

Rooney Mara managed to avoid her beloved black for one evening, but she still looked like quite the drama queen in her art deco Givenchy gown. Although she's still sporting aggressively angular Girl With the Dragon Tattoo hair and makeup, Mara looked as if she could have stepped straight off a 1930s film set. Her accompaniments included a c. 1910 Fred Leighton diamond ring in platinum.
