Put on the pre-stuffed clown belly or secure your DIY padding around your waist.

Step into the yellow satin clown jumpsuit and pull it up over the padding.

Put on your red clown shoes or shoe covers.

Carefully pull on the oversized latex Killer Klown mask, ensuring the eye holes align.

Makeup & hair

If using the mask, no makeup is needed, though you can paint your eyelids black so your skin doesn't show through the eye holes. If going maskless, apply white face paint, draw a massive distorted red smile, and wear a wild red wig.

Tips

Latex masks can get very hot; take regular breaks in well-ventilated areas to cool down.
