Ever wonder what happens after the blank-faced models glide off the runway and disappear backstage at the end of the show? In the case of Saturday's Alexander Wang show, they actually reanimate! Photographer Jeremy Kost has been shooting video for us all week, and he caught the mannequins as they exited the runway and immediately turned into lovely, bouncy cheerleaders. It's actually kind of cute watching them shout "Whooo!" after they've finished walking — the momentary sense of camaraderie is like a high-school sports team, minus the muscle mass.
