Sure, Fashion Week's full of divas, but leave it to Tara Subkoff's Imitation of Christ to put a conceptual spin on things with her "Impromptu Opera/Performance/Party" last night on the Lower East Side. Five opera singers in IOC designs scattered throughout the room, amid a crowd including Kim Gordon, Chloe Sevigny and Natasha Lyonne, sang without notice from wherever they happened every half hour. Our king of Fashion Week party. Below, check out our photos from the evening. Here's a link to an awesome video recap from the IOC folks as well.
