Rooney Mara is known for her avant-garde red carpet style, so when we caught up with the actress at the Academy Awards Nominees Luncheon, we had to ask about her hunt for an Oscars gown. “The most important thing to me is to feel comfortable,” the Best Actress nominee said. “And not just comfortable—but I have to feel good in it. I think that’s really important.” Like her Girl With the Dragon Tattoo character Lisbeth Salander, Mara prefers a neutral palette. “I like simple things. I don’t like to wear anything too crazy. I don’t like that much color,” she told InStyle.com. And she revealed her big pick on the Oscars red carpet tonight—a white Givenchy couture gown!
