Sexy Stars: Zoey Deutch flashes sideboob and Lily-Rose Depp shows off her abs

This week the sexiest styles went to the young talent hitting Hollywood -- and they made sure to put on quite a fashion show.

"Vampire Academy" star Zoey Deutch hit a high note this week in a revealing wool dress from Chanel. The dress itself was relatively modest until the 21-year-old actress wore it without a bra, which showed off some major sideboob as she walked into a party.

Michelle Williams nailed her street style look in skinny jeans and a black blouse at the Cafe Bustelo Pop-Up Cafe this week. 

And while Deutch just went for a hit, other stars went for the full show. Lily Rose-Depp attended the same party as her fellow young star, but she showed off her entire abs in a cropped Chanel jacket and black leather pants. The look was definitely very mature for her 17 years, but admittedly, Johnny Depp's teenage daughter looked like a knockout.

Kristen Stewart also showed off her stylish side this week in a semi-sheer top and cropped pants. She debuted a new hairstyle as well-- which you can hear more about above.
