So this is what Rihanna wore over the weekend to a pre-Grammy party, and it's just ... why? Why is this happening at all? Rihanna looks gorgeous, as always, but it looks like she's just wearing a fancy robe. It's not even like this dress looks like a robe, but I think it could be an actual robe, and someone made a couple stitches at the hip so she wouldn't have to tie it, and then here we are. And really, what the hell is that?
