Do you have the gall to be Vogue editor Anna Wintour for Halloween this year? Then you've got some major competition. Model Snejana Onopka, left, did a spot-on impersonation of Anna in Vogue Paris a while back. Let it be your guide. I first suggest watching The September Issue, you know, as field research. Next, it's imperative to have the following Anna signatures: a perfectly neat bob wig, some form of (faux) fur, dark sunglasses, and slingback sandals with a kitten heel. Also, carry the latest issue of Vogue, hunch over just a tad, and don't crack a smile. I know, it's tough being Anna, but well worth it.
