We love this white Marc by Marc Jacobs dress...


...and when we saw Blair Waldorf (Leighton Meester) on Gossip Girl wearing it in the Hamptons in episode one of the new season of GG we knew we'd seen it before! Paris Hilton had worn it to her fragrance launch at Selfridges in London!

So, who wears it best - queen bee Blair or party princess Paris?
