Wanted: Blair's silk pyjamas

 Gossip Girl Season 4 Episode 6 'Easy J'. I'm perfectly convinced that Blair's shirt and shorts sleep combo was one of the key fashion highlights of the whole episode. And from my googling efforts, it looks like other GGers feel the same. I don't think we've made an id on these PJs yet, so if you've got information- please step forward!
