Some gorgeous gals went glam for a great cause last night.

Uma Thurman, Angie Harmon, Sarah Jessica Parker, Zoe Kravitz and Natasha Bedingfield, plus dapper dudes like Adrien Brody, Kevin Jonas, Mark Ruffalo and Andy Cohen got all dressed up for the 2011 UNICEF Snowflake Ball.

Tickets to the swanky black tie event -- which celebrated UNICEF's work for children -- range from $2,500 for an individual ticket to $100,000 for two tables.
