As a sea of invites floods inboxes across this holiday season, it’s easy to get caught up in the attendant stress. Wednesday night, the ACRIA annual holiday dinner, presented by InStyle and Tiffany & Co., provided something of an antidote. Though held in the capacious 69th Regiment Armory, the event — which aids ACRIA, the nonprofit devoted to supporting HIV research and education, which merged this year with Love Heals: The Alison Gertz Foundation, the largest provider of HIV and sex education in the NYC area — had more the feel of an intimate meal. Art and fashion elites gathered as Amy Astley presented Casey Fremont with the Alison Gertz Young Leadership Award; Jack Pierson bestowed the Artists Ending AIDS Award on the Robert Mapplethorpe Foundation, and Zachary Quinto honored Judith Light with the Elizabeth Taylor Award. “I honestly don’t know how one person could say or do more,” remarked Quinto of Light’s tireless efforts on behalf of AIDS, HIV and LGBTQ activism.
