Halloween Costumes for a White-Blond Bob?

As an adult, my Halloween track record isn’t the best—up until a few years ago, my go-to costume was a black cat. Okay, granted, each year my token feline getup got progressively feather hair extension more scandalous (like every twentysomething girl, I went through a slutty-costume phase). But the past couple of Halloweens I’ve tried to be more creative. Two years ago, I went dressed as (a less scantily clad) Jennifer Beals from Flashdance. To mimic her mass of ringlets, I twisted my damp hair into a million different braids the night before and let them all hang loose the next day. (An oversized sweatshirt combined with funky leggings and legwarmers and I was ready to bust a move!) Last year, I let my lace wigs now-cancelled TV show Terminator: The Sarah Connor Chronicles. Using fake blood and silver eye shadow I attempted to create a terminator-like wound around my eye, but only succeeded in looking like a victim of skin-eating bacteria. Nevertheless, my black biker jacket and the “come with me if you want to live” logo emblazoned across my t-shirt provided some fellow sci-fi nerds with clues…So now we come to this year—as you may have seen, I went to the M.A.C Pro Store in Chelsea to get transformed into Lady Gaga for ELLE.com's Halloween Makeover video. As much as I love her music, though, I’m not sure I want to be Gaga for Halloween. Because, for one thing, I’m sure I’ll get upstaged by some fabulous-looking drag queen (according to the M.A.C Pro Store, most of the Lady Gaga makeup requests have come from men!). Which leaves me between a rock and a hard place—or does it? The other day, I was hit with the idea of being (again, a more conservative version) of Julia Roberts in Pretty Woman. You know, when she’s hot off Sunset Boulevard and waltzes into the fancy-schmantzy hotel for front lace wigs the first time. Though I’ll pass on baring my non-existent six-pack, over-the-knee boots are hot right now and I think that, combined with my wig, it could make for a good combo. On the other hand, I’m still superobsessed with the Mad Men era and could easily turn out a Twiggy or Edie Sedgwick look.What direction do you think I should go? Or, better yet, do you have any more ideas on how I can utilize my white-blond bob from Ricky’s NYC? Let me know!—Emily HebertFollow ELLE on Twitter
