Kim Kardashian helped her little sister Khloe celebrate her 27th birthday in where else, Vegas! For the big party she wore a Hervé Léger dress from the Spring 2011 collection. And she completed the sexy look with a pair of Christian Louboutin "Daffodile 160" pumps. I love this dress, and I love this entire collection. In my opinion Kim even wore the dress better than the runway model!
