A pretty swanky crowd turned up at MoMA last night for the Armory Party, which kicked off the Armory Fair (check out our guide to this year's festival HERE) and featured a performance by Solange and Dev Hynes. Click through for photos of cute kids like Alexa Chung, Harley Viera-Newton and, of course, Solange and Dev. (We also hear there was a Jay-Bey sighting in the wings but, alas, you could barely see their silhouettes, much less get past security for a photo.)
