The Cannes Film Festival isn't complete until amfAR's annual Cinema Against AIDS gala goes down.

Fashion's boldest names turned out the strongest looks, including Joan Smalls in a pseudo minidress, Karlie Kloss in a chic, tailored suit, and Anna Dello Russo in gam-flashing ruffles. No attendees disappointed, though, making for one very glamorous affair. Click through to see who's wearing what at the 2013 amfAR benefit.
