Yikes! You're rapidly becoming my favorite TWF member
(I think I've got at least 4 costumes from there... soon to be 6, as I need both a Pirate outfit, AND a Halloween costume for this year... but I've got Little Red Riding Hood, Naughty Cop, Santa's Helper, and Wizard Schoolgirl)
(and FWIW, their customer service is excellent... as in I've ordered on a Sunday, and had it on my doorstep Monday afternoon). Order your wife somethin' ... You'll be glad you did.
Halloween is funny. All girls just dress up as whores. They may have some name for what the costume is (nun, school girl, nurse, police officer, etc.) but they all just dress up as dirty whores. I love it, though.
My buddy dressed up as a GIANT 40oz bottle of colt 45. Made a had with tinfoil to be the cap and everything. It was awesome.
