we always go the gory route...one of my fave's is Little Dead Riding Hood and the Big Bad Wolf...I have one of my arms hidden inside my blouse( the red cape helps hide it) and we have a fake one in the "Wolves" mouth....one of the fake rubber ones you buy.
Dead Bride and Groom, Vampire and Bat, pirate /wench, I hear Bernie Madoff is popular this year..you could be a riches ro rags high society type and your DH could be Bernie..or there is Al Gore and a polar bear,
one of our tackiest...( I admit it was REALLY tacky, but it was perfect for the theme of the party) anyway...I was a stewardess from US Air, the year they had a plane crash...I was basically like a zombie and my mantra was US.Air, we almost get you there" and DH was one of the pilots, also zombie .
And the SCARIEST costume ever?
DD went as a "student loan" once ...

yep, that is

She and her BF won a contest at college last year as Sweeney Todd and Mrs. Lovette...complete with pie with body part emerging out of it....like I said, we go the gory route,
Have fun deciding!
