Many fashionable Hollywood celebrities turned up the glamour at last night's amfAR Gala at NYC's Cipriani 42nd Street. The event, which helps kick off New York Fashion Week, was full of designers and celebs in stylish gowns. Ashley Greene wore a white Giambattista Valli frock while Sarah Jessica Parker went for a daring Maison Martin Margiela Couture pink dress. Honoree Heidi Klum donned a black Michael Kors number, which she wore when she chatted with the designer and her former Project Runway costar on the red carpet.
Other guests included Cheyenne Jackson, Chloë Sevigny, couple John Legend and Chrissy Teigen, and Game of Thrones star Emilia Clarke, who dazzled in a dramatic Zac Posen gown. Of course, the night wasn't only about fashion — the amfAR Gala benefits AIDS research and honors those who have made significant contributions towards the fight against the deadly disease. In addition to Heidi, designer Kenneth Cole and Janet Jackson were honored for their work with the organization.
