Oh how I love a good "who wore it better?" challenge. But I've literally never seen a look repeater so close together. As we've already seen Rumer Willis stepped out in Stella McCartney for the LA premiere of her movie Sorority Row last Thursday. Meanwhile the next morning in France, Rachel McAdams donned the exact same Stella McCartney lace blouse at the Deauville Film Festival opening ceremony. Both ladies kept the look monochromatic in all black, but this is proof that you really can do so many things with just one piece. While Rachel kept the look very ladylike by tucking the blouse into a black tulip skirt and pairing the whole thing with black peep toes, Rumer's look felt younger and fresher loosely laired over black skinny pants and pointy black pumps. Not to mention that Rumer's dark makeup added a rocker chic element to the very feminine lace.

What do we think? McGosling or a member of the WIllis/Moore/Kutcher clan?
