Rooney Mara continued her red carpet tear this week in all-white Givenchy while Carly Cushnie and Michelle Ochs provide a nice counter wearing their own designs in all-black at a dinner honoring Grace Mirabella hosted by Paul Sinclaire and Joe Mimran. Rachel McAdams and Michelle Williams added prints, in Peter Som and Erdem respectively, while Blake Lively and Keira Knightley kept things ladylike in Valentino and Burberry.
