Civil War Nurse:
Find a really long skirt. Then make a hoop for it. Find a dress shirt that is white. Then buy a Dracula cape and cut of the collar of it . Then find a hair net. Then after that find a white apron. Tie the apron around. Use theatrical blood on the apron to make it look like that you were doing surgery on some one and that's it.
Thanks to David for this great idea!!!
