The beautiful actress stepped out in an event supporting Jason Wu in one of his Fall 2011 runway looks. The black dress was perfection on Diane because she kept it simple with a chic side braid and nude satin pumps. The only thing I would change is the long gold earrings, the dangling style didn’t match the simplicity of the dress. Overall though, Diane looked stunning as usual. This Fall 2011 Jason Wu dress is available at AlOthman. Hurry up if you want it though, there is only one piece left!
