One of the scariest movies of all time, The Exorcist is an American horror classic. Dress up like poor possessed Regan with our Regan Exorcist Women's Costume with Wig. It comes with a wig and a nightgown designed to look like the one she wore in the movie. Pale green nightgown with spots and lace trim is spattered with blood and green vomit stains. Tousled auburn colored wig When young Regan starts acting up in school and shows surprising strength, her mother starts to worry. This is nothing compared with the terror that follows. Order a demented looking horror mask and some faux dirt to appear as though an evil spirit is pulling the strings and using your body as a vessel for evil.
