While we're used to seeing Olivia Wilde in pretty bohemian gowns or sexy dresses, the actress showed off a different style on the red carpet at the Cowboys and Aliens premiere in the UK. Taking a turn towards the classics, Olivia donned a black and white sheer polka-dot Gucci gown paired with Brian Atwood pumps, red lipstick and a bumped-up hairdo. Look closely and you'll notice her dress is far from conservative thanks to the sexy sheer side panels. Tell us, what do you think of her classic-cum-vamp ensemble.
