This dress is…whatever. It’s neither the worst thing Sienna Miller has ever worn, nor the best, and I suspect we will all forget it even happened by Wednesday. And my suspicion is that Sienna Miller’s stylist saw this on her and muttered, “everyone is going to forget this even happened by Wednesday” and decided that the answer to that was…pearls. Loads of them! And a lank ponytail finished off with a bow, to, uh, really, uh, cement the ’50s sock-hop feel of the jewelry? Hey, they took a shot.
