Last night Gemma Arterton attended the Net-A-Porter 10th birthday party in the same Prada dress we saw Kristen wearing in the Elle UK June 2010 issue. The dress in question is from the Prada Fall 2010 collection and features a balconette of lace ruffles along the bust area. The ruffles being a key feature of the dress were watered down for Gemma’s version therefore I'm personally going with Kristen on this one.
