On Monday night several actresses including Jessica Alba, Naomi Watts and Kerry Washington turned out to honor Ralph Lauren at a swanky party in New York City thrown by Oprah Winfrey.

And while all of the ladies looked gorgeous in their Ralph Lauren gowns (natch), one star stole the spotlight in a major way.

Camilla Belle wore a skin-tight black creation from the designer's Fall 2011 collection, which featured a sheer, sleeveless top, beaded bodice and glamorous feather train.

"Luckily this one fit perfectly. From the top to the bottom, there's so much detail," the star, 25, told Us Weekly at the event. "It's really beautiful."

Belle slicked back her hair, showing off a pair of Cartier diamond earrings and went for a bold pink lipstick (celebrity makeup artist Hung Vanngo used Tom Ford Lip Color in Violet Fatale).
