Rooney Mara Met Gala 2013: Star Looks White-Hot In Low-Cut, Zip-Up Gown (PHOTOS)

Rooney Mara dressed in head-to-toe Givenchy for the 2013 Met Gala, held at the Metropolitan Museum of Art on May 6 in New York City.

The 28-year-old actress flaunted her cleavage -- and incredible figure -- in a low-cut white gown, which featured zipper and lace details.

Mara was a co-chair for this year’s Costume Institute Gala Benefit, celebrating the opening of the "Punk: Chaos to Couture" exhibition. She was joined by Moda Operandi creative director Lauren Santo Domingo, Givenchy designer Riccardo Tisci and Vogue editor Anna Wintour.

"It's an honor and I'm so honored to do it with Riccardo," Mara told the Associated Press. "I'm also honored because of the punk theme and I'm happy to be here."
