Several celebrities attended the amfAR gala held at Cipriani Wall Street in New York City on Wednesday, showing off their figures in designer duds. The event kicks off New York Fashion Week.

Heidi Klum unsurprisingly stunned in a shimmering Michael Kors black gown with a plunging neckline. She wore a jeweled necklace by Lorraine Schwartz.

Ashley Greene wore a white, goddess-like Giambattista Valli gown with a gold laurel leaf belt, while Lindsay Lohan opted for a metallic vintage Roberto Cavalli dress.

Sarah Jessica Parker, often lauded for her fashion sense, chose a fuschia Maison Martin Margiela Spring 2013 Couture gown with an unusual black and white scarf. Doutzen Kroes looked lovely in a strapless, floor-length peach gown.

amfAR focuses on creating and implementing HIV research, treatment, prevention, and education strategies in developing countries.
