A look that evoked cool and classic, but seemed suddenly brand new? One-shoulder dresses. Reese Witherspoon looked every bit the California girl in her understated one-shoulder gown only rivaled by Jennifer Taniston (drool, Brangelina — and John Mayer, drool), who radiated California-cool in her black one-shoulder Valentino dress. The standout beauty of the night? The very French and fabulous Marion Cotillard, whose Christian Dior dress was almost as pretty as the actress herself. The newly engaged Jane Krakowski was no slouch either in her single-shouldered Golden Globes dress by J. Mendel.
