The sun set over Ross Bleckner’s Sagaponack home as guests showed their support for ACRIA (benefiting AIDS research). The Cocktails at Sunset event brought together the Hamptons oh-so-social crowd, including Calvin Klein, Rory and Elie Tahari, and David Salle.

Banana Republic and InStyle hosted the event, with the help of Beth Rudin DeWoody, Gillian Hearst-Shaw, and Martha Nelson. Paul Sevigny took over the deejay booth, and dancing was followed by an auction featuring many luxuries, including one-of-a-kind works of art by Bleckner himself.
