Things You'll Need
Navy mechanics suit
Heavy work boots
Fake rubber knife
Michael Myers, the murderous star of the "Halloween" movie franchise, is a perfect Halloween costume. His face is all white, and there's nothing fancy about his outfit. Use a Myers photo as a guide, but if the face, hair and basic uniform are right, trick-or-treaters should be able to tell who you are.
Apply some stains to the mechanic's suit. Myers is usually seen in this suit, and the stains represent blood. Keep the knife in a pocket. Walk around in the boots to ensure you can wear them comfortably.
Use makeup to paint your face white. If you prefer to stay hidden behind a mask, paint any plain mask white.
Fix your own brown hair to stand upright. If you do not have wiry brown hair, wear a wig.
Perfect his body language. Michael doesn't talk. Tilt your head slowly to one side when someone is talking to you. Walk stiffly; Michael is never loose and never runs.
For special effects, occasionally play the "Halloween" theme song. Keep it queued up on a tape recorder hidden in a pocket of the jumpsuit.
