How to put it together

1
Unbox your foam Porta Potty tunic and steam out any wrinkles so it holds its boxy shape.
2
If using the fake legs illusion, securely pin or velcro the stuffed jeans to the front cutout of the toilet seat area.
3
Attach the 'OCCUPIED' sign to the front door flap using double-sided tape or safety pins.
4
Loop a string through a real roll of toilet paper and hang it from your shoulder or attach it to the side of the tunic.
5
Hang a pine-tree air freshener around your neck for an extra sensory laugh.
6
Slip the tunic over your head, aligning your face with the open window or door cutout, and wear comfortable dark clothing underneath.

Makeup & hair

Keep your hair simple or wear a funny baseball cap. For makeup, you can paint a comical 'strained' expression or keep your face completely natural since your head will be peeking out of a giant plastic toilet box.

Tips

Make sure the armholes are wide enough so you can easily hold a drink or navigate through crowds at a party.
Wear lightweight, breathable clothing like a black t-shirt and shorts underneath, as foam tunics can trap body heat.
If building a DIY cardboard version, ensure the bottom of the box ends above your knees so you can walk and climb stairs safely.
