It wouldn't be a Costume Institute Gala without models. Lots of models. Remember last year the whole theme and exhibit was an ode to the impossibly beautiful ones? Last night many lovelies showed their support in looks ranging from a gold lame Michael Kors jumpsuit (go Chanel Iman!) to a sexy white cutout Altuzarra (Karolina) to Coco in a wondrous Zac Posen cloudy confection.
