From Gossip Girl: "Those are pants. That she wore on purpose. I assumed her actual garment had been whisked off in a horrible accident on the way to the Rolling Stones concert in LA (tres typical that she’d be there, considering she thinks she’s Stevie Knicks’ daughter) and she had merely used some nice lady’s curtains as a temporary outfit. But no. Not only that but they show off her tacky underwear–never a do, darlings."
