Alright y'all, I don't know the context of these two looks or when they'll be airing, but I do know the designers. Leighton Meester is wearing Ralph Lauren and Blake Lively is in Zuhair Murad.
I'm not a huge fan of the Ralph Lauren look. It doesn't seem very flattering, and the baby blue is killing me. The Zuhair Murad look, on the other hand, is fab. I love the play on sheerness, but purple-grey hue, and how it manages to be both dramatic and formal, and yet very sexy.
