See what I have spotted on the fourth episode of Gossip Girl. It's the New York Nat's Belvedere Castle headband that I featured in one of my post about hair accessories.
The headband was worn by one of the girls during Blair Waldorf's Annual Sleepover. It was made of silk with tulle and Swarovski crystals. If you want to channel this Gossip Girl look, use this headband as an accessory to your black dress.
You will find the rest of New York Nat collection at Blair's favorite store, Henri Bendel Fifth Avenue.
