Mischa Barton sported some wildly unflattering sweats on the set of her new movie Homecoming in LA on Thursday. At least she finally got rid of those too-blond locks. In the movie, Mischa plays a girl who gets back at her ex after he moves on with a new lady. Looks like she's already channeling her inner bad girl by walking around with no shoes on. Couldn't her Keds sponsors help her out with that?
