Lmao! Shocking :)
I remember the last time I got dressed up for Halloween, in college. My two best friends (2 guys) and I wanted to take advantage of a free cover for those who bothered to dress up, but we didn't have any costumes, so we had to improvise at the last minute. I just wore some normal clothes (Leather jacket and black jeans) and wrapped a belt around my neck, and draped them up in black curtains. When asked at the door who I was supposed to be, I said something to the effect of, "I am Mistress Malvolent Millicent and these are my minions... muahahaaa!!!
It was a great excuse to go out all publically decked out in low key sm gear :D
