The amfAR New York Gala isn't just a haven for stunning celebrity red-carpet looks; it's also for a good cause. The annual event has become one of the city's most successful and high-profile AIDS benefits, saluting some of the biggest names in entertainment, fashion, and art. Lucky for us, it never fails to bring out a slew of stylish do-gooders — and tonight's event did not disappoint.
It was a black-and-white kind of night for heavy-hitters like Heidi Klum  and Karlie Kloss (both clad in Michael Kors), Hilary Rhoda, and Chrissy Teigen, who all donned dresses in the graphic color palette. Sarah Jessica Parker  went with a bright pink strapless sheath from Maison Martin Margiela, while Crystal Renn went for full-on glamour in a striking red gown.
