Mary-Kate Olsen attended the 2009 Tribeca Film Festival LA Kick-Off Event at the W Hollywood Hotel the other night, and the starlet looked pleased to mingle with her fellow thespians, but what's with this outfit?!

This is MARY-KATE for crying out loud - we expect more from her than a normal, neutral toned ensemble!
