Rooney Mara consistently steps out in one amazing design after another. And while we here at InStyle can always appreciate a killer red carpet look, it's the Golden Globe nominated actress's approach to fashion that really has us taking a closer look. How does she do it? She plays with the same color scheme (white, black, and shades of cream) and the same designers, typically Chanel, Alexander McQueen, and Givenchy, but she always manages to turn heads with her unique style. Here, browse 20 of Rooney Mara's best red carpet looks for a serious dose of eye candy.
