NYC's elite were out to show support and show off their designer duds, for one of fashion's biggest nights. Every major star from music, fashion and film strutted down the carpet at the annual Costume Institute's Met Gala. Beyoncé, always a showstopper, wore a sheer Givenchy gown that showed off that post-baby body. Fashion risk taker, Rihanna donned a slick, black, Tom Ford dress. While first timer, Nina Dobrev, looked stunning in a black and gold Donna Karan Atelier gown.
