Emma Watson wowed at the Perks of Being a Wallflower premiere in Los Angeles last night in a nude backless dress.

The actress chose to wear a dress with a three-tiered lace skirt, featuring crystal embellishments all over.

Slim spaghetti straps criss-crossed at the back, which dipped into a low-V at her waist.

The Harry Potter star went for a fashion-forward wet-look hairstyle, wearing her tresses pulled back in a slick chignon.

She kept her makeup classic and simple with subtle brown eyeshadow, matte red lipstick and flushed cheeks.

Watson's co-star Nina Dobrev also went for a daring look on the night, choosing a low-cut mini red dress by Reem Acra. The Vampire Diaries actress teamed her lace, long-sleeved frock with Rupert Sanderson heels.

Rumer Willis went for a black floor-length number, which featured lace at the neckline, cut-out detailing at the waist and two thigh-high slits.
