This one is for an older pre-teen type. Definitely creepy. The mask was purchased as was the 'fake' butcher knife. Simply wear an old sweatshirt and old track pants. Rough up shirt and pants with black and red Halloween paint or fabric paint. The knife is inserted into the shirt by attached a piece of Styrofoam to the underside of the shirt. Cut a slot in the Styrofoam before attaching so the knife with tightly fit in. Use fake Halloween blood to put around knife, on hands and perhaps on shirt.
