The AIDS Community Research Initiative of America (ACRIA) hosted its annual “Cocktails at Sunset” benefit July 23 at committee member (and superstar fashion photographer) Steven Klein’s home in Bridgehampton, New York.

The event featured a silent auction including trip packages, watches, art and more to benefit ACRIA’s work. Champagne flowed throughout the night, and music was provided by DJ trio The Misshapes who kept guests dancing into the twilight hours.

Celebrating the theme of the night—“AIDS isn’t taking the summer off and neither are we”—were celebrity guests Olivier Theyskens, Calvin Klein, Jill Stuart, Nacho Figueras, Rachel Zoe and many more.
