Margot Tenenbaum
The ideal mix of hipster and WASP, Margot Tenenbaum as portrayed by Gwyneth Paltrow is a classic for Halloween inspo. Grab a brown fur coat, striped polo dress, and a cigarette to keep in hand and/or mouth perpetually throughout the evening. If you can't snag a blonde bob wig in time, ultra straight hair and a single barrette will do just fine. Oh, and don't forget the heavy black eyeliner.
