Beautiful dress, until I saw the backside. I would have said she elegantly pulled the look off, with just the right amount of sexy. But no she didn't. She resorted to what every woman in hollywood pretty much does... Show of their ass and leave nothing to the imagination. If she was looking for attention... she got it! I say she pulled it off because that's what it seems she was looking for.
Something off topic... I can't believe how some people say she looks like Rihanna. I see no resemblance at all!
