Leighton Meester enjoys a sit down dinner inside the 2012 amfAR New York Gala held at Cipriani Wall Street on Wednesday (February 8) in New York City.

The 25-year-old Gossip Girl actress dolled up in head-to-toe Louis Vuitton for the big event.

The gala helped raise funds for amfAR, which is dedicated to the support of HIV/AIDS research, and also kicked off New York Fashion Week.

Earlier this week, Leighton was spotted filming new scenes for the CW show with costar Penn Badgley.
