Who's that girl with the plunging neckline? It's Rooney Mara!

The "Girl With a Dragon Tattoo" star arrived at Tuesday night's Costume Designers Guild Awards in a revealing plum gown. Her make-up -- matching plum lip and tinted brows -- was a lot more glam than the minimal looks she's been sporting lately. Hopefully Rooney will continue this trend through Oscar Sunday!

Also at the event was Chloe Moretz (with pink streaks in her hair) and the always glamorous Kate Beckinsale. Click on the "Launch Gallery" button below to see even more photos from the event.
