Sienna Miller showed off her new hair color and summery dress while walking the streets of London the other day. She's been busy filming The Best Time of Our Lives with Keira Knightley and doing ads for Tod's latest campaign. In the ads she looks super glam. I prefer that look over this disheveled one but at least she always has some style - even if it includes some misses like this one. Does anyone else have the same urge to tuck in the hanger strappy thing that's hanging out???
