What they wore: A black Gucci Spring 2013 gown with ruffles at the halter neckline and along the open back.

When they wore it: Jenner rocked the dress during a March 1 photo shoot for the cover of Harper's Bazaar Arabia. For Biel, the November premiere of her movie "Hitchcock" in Beverly Hills was the perfect occasion to don the dramatic design.

Judge's scorecard: This is one sexy dress! Biel's updo is gorgeous, and keeping it out of the way puts more of the focus on her glam garment. However, Jenner looks amazing — maybe even a little too grown up for someone who's not yet old enough to vote!
