Rooney Mara: Costume Designers Guild Awards 2012

Rooney Mara attends the 2012 Costume Designers Guild Awards at The Beverly Hilton Hotel on Tuesday (February 21) in Beverly Hills, Calif.

The 26-year-old actress – in a J. Mendel dress with a plunging neckline – met up with The Girl With the Dragon Tattoo costume designer Trish Summerville on the carpet.

“[Award season has] been an amazing experience. I’ve been lucky that I’ve been surrounded by really amazing people, so it’s been great,” Rooney recently told reporters.

“It seems crazy when I’m in a setting like this, but then I just go home and life feels very normal,” she added.
