Layered Necklaces on the set of Gossip Girl Season 3

There has been a retro feel on the set of Gossip Girl recently. The cast and crew are currently working hard on the third series but my girl PopSugar UK has been providing us with sneak previews of the action happening in the Big Apple. Hilary Duff has joined the show and got in to the '20s revival. I noticed that both Hilary and Taylor Momsen have been spotted in layered necklaces which is sure to spark a comeback. See below for some gorgeous items available now, including a couple of gorgeous pearl pieces by Lanvin.
