Niece is throwing a "Friday the 13th" costume party at my In-laws house on Friday. I literally have NO clue of what to be. I know it has to be something on the spookier side (as that's what's done here), but I've just been soo busy with a lot on my plate lately that I haven't really had a chance to think and prepare anything and now my brain is just blank.... Any ideas that don't involved just splattering fake blood on myself wearing whatever?
The easier it is to execute (or, I guess, the more cost effective), the better.
