Certainly didn't see this coming. The Costume Designers Guild bestowed their prize for Excellence in Period Film to Madonna's reviled W.E., only half of which is period, and the only Oscar nominee I haven't been considering as a viable winner. Figures. Well, congrats to Arianne Philips. Having been unable and unwilling to see the film, I can honestly say I have no comment.
Meanwhile, my hunch that Harry Potter would receive guild approval panned out, while the dark hued modern threads of The Girl with the Dragon Tattoo took home the Contemporary award.
