I'm sure this looked better in the flesh, but in this photo, the fabric just looks like shiny sandpaper. Funny how some dresses don't translate to the camera. I mean, it's nice and you can tell it would be lovely if it were actually in front of you ... but not the best choice Cameron has made in her stylish life. It might have something to do with her pissed off stance. She's all "hurry up and take the photo people! I have a party to get to!"
Well that's what I would be thinking if I were her.
