It appears Mandy has cleaned up her act a bit since her vintage attempt at the Grammys [0]. Here she is waiting around looking buttoned up and cute in one of my favorite designers. I just saw her last movie "Because I Said So" and I have to admit MM is a keeper. Let's hope she keeps up the good style work.
