One of the best moments in the movie Mean Girls has to be when high schooler Cady enters her friend’s Halloween Party dressed as a vampire bride, complete with gory make-up, ghastly wig, and a mouth full of broken teeth. As she looks around at the array of strip club dancers, Playboy Bunnies, sexy mice, sexy cats, and sexy witches, her girl friend, horrified, corners her: “Why are you dressed so scary?” “In the regular world” Cady comes to see, “Halloween is when children dress up in costumes and beg for candy. In Girl World, Halloween is the one night a year when a girl can dress like a total slut and no other girls can say anything about it.”

Not even close. Girl World and regular world collided years ago, and in a perverse co-optation of Girl Power, mini versions of sexy women will be winding their way through the streets of America this Halloween. They’ll have bought their French maid outfits, pink pussycat fishnets, Catholic school girl peek-a-boo skirts, and midriff baring Bad Girl University cheering sweaters at a mainstream box store near you.

This Halloween we’re supporting all those little rebel Cady’s of the world by bringing scary back – along with creative, funny, clever—even sarcastic. Join us by entering the First Ever Intervene On Halloween Costume Contest! Share your outrageous, frightening, brilliant, gorgeous costumes and have the chance to WIN and really get noticed!

Here’s the deal: you can submit pictures, past and present, of your scariest and most unique Halloween costumes as a comment here, on the SPARK Facebook page, on the Hardy Girls Healthy Women Facebook page, or on the Intervene On Halloween Facebook Event. Two great categories, two fab prizes: We’ll send the winners (must be over 18) on an all-expense paid trip to NYC to attend the SPARK (That’s Sexualization Protest: Action, Resistance, Knowledge) Summit on Oct. 22nd.

But even if you don’t win, we’ll include your costume in a slide show to be shown on the Summit day and on theSPARK website!

Don’t have a photo of yourself decked out in Halloween terror? Have no fear (well, you can have a little – its Halloween after all!). Take part in Halloween SPARKwatch: What’s the most ridiculously sexist, sexy or sexualized costume you’ve seen? Sexy ‘Finding Nemo?’ Post a picture on our SPARKwatch Facebook Event and tell us where you found it! We’ll send each and every photo back to the costumer’s manufacturer, with a SPARKwatch “Stop making Halloween an excuse to objectify and sexualize girls” message!
