I refused to give up until finding what designer J. Law wore to this morning's announcement. The result is in the title and I was so enamored by this look that I couldn't wait until Sunday to talk about it. This is a custom made Prada dress from the Spring 2012 collection. Lawrence had it altered to fit with a pencil skirt while keeping the girly, playful top. I love the lemon and baby blue with the black fabric of the skirt and her hair is to die for. Anyway, proceed with your da night!
