Olivia Wilde Goes Braless In Racy Black Suit For 'Rush' Premiere

Little black dress? Not for this girl.

Olivia Wilde stepped out in London on Monday night in a little black pantsuit that left nothing to the imagination.

The "TRON: Legacy" actress went braless to attend the world premiere of her latest film "Rush" with co-star Chris Hemsworth (yes, whose little brother Liam is Miley's fiance -- or something.)

While the navel-grazing neckline may have been a fashion risk for someone else, the sleek, black Gucci tuxedo looked tasteful and sexy on the tall, leggy 29-year-old actress. Olivia kept accessories to a minimum, wearing earrings, simple black pointy pumps and bright red lipstick.

In "Rush", Olivia plays the role of Suzy Miller who models a variety of amazing Gucci archive creations, so her choice of designer for this event is unsurprising. The bare chest and satin lapels are reminiscent of Jennifer Aniston's 2002 Golden Globe's outfit: A simple black tux with flared pants and blingy diamond necklace.

Speaking of Aniston, she was most recently in a film with Wilde's fiancé, funnyman Jason Sudeikis. We bet Sudeikis feels pretty great about his girl -- or maybe he's jealous that she can rock a suit better than he can.

Olivia's come a long way!
