Last night the rich, famous, recession-proof and beautiful came together under the roof of the Met for the annual Costume Institute Ball, in celebration of the museum's new exhibit called Model as Muse. While last year the theme was superhero, this year's was supermodel, and Style has a thorough rundown of the glamorous night (that the NY Post thought was more Zoolander-inspired). The evening wasn't without some drama, of course, the NY Times reports that designer Azzedine Alaïa wasn't included in the exhibit, so some of his muses, like Naomi Campbell, refused to attend. There were still plenty of best and worst dressed to gawk at, however.
