Man in a Box Costume
Trick the crowd with this classic, hilarious optical illusion box costume.
The Man in a Box costume is a classic optical illusion that makes it look like you are being carried inside a cardboard box by another person (or that your upper body is emerging from a box while fake legs dangle). It is a favorite for Halloween because of its high-impact visual comedy and DIY-friendly nature. The look consists of a real cardboard box worn around your waist, paired with stuffed fake legs on the outside and your real legs hidden below.

How to put it together
- 1
Cut a hole in the bottom of the cardboard box that is wide enough for your waist and hips to fit through comfortably.
- 2
Secure two heavy-duty suspenders or webbing straps inside the box, crossing them over your shoulders to support the box's weight at waist height.
- 3
Stuff the fake pants tightly with fiberfill or newspaper, leaving the top waist area flat so it can be secured to the box.
- 4
Attach the stuffed pants to the top front edge of the box using heavy-duty duct tape, zip ties, or hot glue, making it look like legs are hanging out.
- 5
Fasten the lightweight shoes to the cuffs of the stuffed pants using safety pins, tape, or glue so they do not fall off.
- 6
Step into the box, pull the suspenders over your shoulders, and put on your flannel shirt over the suspenders to hide them.
- 7
Let the stuffed legs drape over the front of the box while your real legs walk freely underneath.
Makeup & hair
Keep your hair and makeup completely natural and casual, as the focus of this costume is entirely on the physical optical illusion.
