Margot Robbie wore a Saint Laurent black, long-sleeve gown with a plunging V-neck top and Van Cleef & Arpels necklace on the red carpet at the 2015 Academy Awards held at the Dolby Theatre on Sunday (Feb. 22) in Hollywood. 

Robbie was a lesser-known Australian actress until her performance in last year's Oscar-nominated picture The Wolf of Wall Street, a role which skyrocketed her onto the A-list.
