Ok, clowns, here's the almost-finished product.  My friends are providing the blonde wig, striped armbands and fishnet stockings.  I'm wearing calf-high black boots with it.  No pics of me *in* it yet, because as I just explained, it's not finished.  Ish.  A friend of mine is going as "modern" Ivy, (auburn wig + green clothing...yay),another is going as Two-Face, complete with professional prosthesis, and everyone else in our group is opting simply for a Batman shirt of some kind or Joker makeup.
 
 
And to all the SUPER CEREAL internet tough guys dissing the costuming stuff- lay off.  Clearly you do not appreciate the culture of a midnight movie.  Have you ever heard the song 
The Freaks Come Out At Night?  (Term used lovingly, of course) Especially for hyped-up, big release "geeky" movies like this, yeah, you're gonna see a lot of costumes.  Don't want to see costumes?  Go to the 3-o'clock showing in Bootlick, Nebraska.  Let us "geeks" have our little party. (And this coming from a part-time model/actress) After all, midnight on July 18th, 2008 only comes once.
