Olivia Palermo a the 2011 Green Auction: A Bid To Save The Earth at Christie's Auction House in New York.
Olivia wore a black beaded Rachel Roy top plus a black-and-lilac skirt and snakeskin pumps.
Coming from the Pre-Fall 2011 collection, Olivia's top isn't available and her skirt is from a previous Topshop by Marios collection so is no longer available either.
