Keira Knightley may have lost out to Patricia Arquette for Best Supporting Actress but she won the red carpet in her stunning creation from Valentino's spring/summer 2015 couture collection. The dreamy dress, decorated with flowers and extracts from French poetry, looked amazing on Keira's growing bump. The Imitation Game actress also chose Valentino for the Vanity Fair after party: a beautiful inky gown with a plunging neckline and flowing train.

American Sniper and Foxcatcher star Sienna Miller chose Peter Copping for Oscar de la Renta for the ceremony and her lace dress was hot off the catwalk: it made its debut at New York Fashion Week only four days earlier. The intricate lace dress with delicate velvet bows and semi-sheer skirt perfectly epitomises the rebirth of the house of de la Renta following the iconic designer's death last October. Miller accessorised with a black clutch and pearl bangle and looked as elegant yet contemporary as ever.
