Best Actress nominee Carey Mulligan was dressed in honorable style for the Everlon Diamond Knot Collection Luncheon, held for her at the Chateau Marmont.  The young actress looked gorgeous in a 1950’s inspired yellow and white dress, which had a summery feel to it.

Twilight star Nikki Reed was almost flawlessly fashionable…but slipped up by wearing motorcycle boots with a beige mini and black blazer.  Ginnifer Goodwin followed in the vintage-feeling footsteps of fellow pixie Carey, wearing a fringed-sleeved jumpsuit from Moschino with Aldo heels.
