I think part of the reason that she's not walking the Couture shows is that IMG said they'll be picking and choosing things she ought to do, and I'm thinking that on an image basis, Couture isn't so "up and at em" anymore the way it used to be - designers have cut a lot of their couture shows (shame, really) so maybe they decided that they wanted to keep her in editorials, advertisments, and rtw runway shows??
