Those in favor of the sexification of Halloween will be happy to know the trend is alive as ever, and the market for such attire seems to have expanded. Jezebel has a roundup of the sexy selections available at your costume-in-a-bag retailer of choice, including Sexy Nemo (sexualized cartoon fish), Sexy Chinese Take-Out Box (sexualized grease-box of rice) and Sexy Skunk (sexualized stink animal). There's even a Sexy Anorexia costume ("Anna Rexia") for those of you who believe that nothing tastes as good as skinny feels (but can totally laugh about it!).
Also, if your idea of sexiness has more of a 1970s porn movie aesthetic, American Apparel has some ideas for you.
The only thing Frenchman Street Halloween revelers value more than sexiness in a costume is something that's New Orleans-centric. So, to create the ultimate costume, you need to have the perfect combination of Nola.com-headlines-from-2011-ness and "I'm totally just wearing lingerie." Here are a few ideas to get you started:
Sexy Marsh Fire: Black feather boa ("smoke") + bra and underwear (the "fire" represented by your hotness, obviously)
Sexy Uptown Coyote (or any other scary animal in an urban setting that had a parody Twitter account at one point): species-ambiguous animal ears + bra and underwear
Sexy Saints Player: team jersey + black lines drawn under eyes + no pants
Sexy Oil Spill (still relevant!): black paint poured all over yourself + bra and underwear
Sexy Tony the Tiger From Controversial Baton Rouge Truck Stop: tiger ears + tiger tail (available wherever LSU things meant to hang from truck beds are sold) + bra and underwear + look of sadness due to forced captivity
