If you have a black dress and any tip with a white collar, you've got Wednesday Addams. Probably one of my favorite last minute costumes. Even though my hair isn't long enough for braid pigtails, I think the look is still very of the character. And I just happened to have a hand..uh, on hand, as Thing! I don't have any headless dolls (anymore, that ship has sailed) so the hand will do.

I have a couple more costume post ideas up my sleeve, but I'm open to any suggestions! Like I said, my closet has lots of stuff for me to whip up lotsa looks.
