Alternatively, stuff your bald cap with cotton batting instead. [3] X Research source Don’t worry about gluing the batting down; the bald cap will help hold it in place.

A bald cap is not the same thing as a swim cap or a wig cap. You need to buy it online or in a costume shop. The color doesn’t matter. If there’s too much bulk in the seams, pull the cotton batting downward with your fingers. Be careful so that it doesn’t peek out from under the cap, however. If you choose to leave your ponytail out, you’ll need to tuck it under the rest of your costume.

Double-check your front hairline and glue down any other edges that appear loose. Spirit gum is a theatrical-grade adhesive used for prosthetics. You can find it online and in costume shops.

Make sure that you get the front and temples, all the way down to your ears. Wait 1 to 2 minutes for the liquid latex to dry, then apply another coat, if needed. If the liquid latex is taking too long to dry, speed the process up with a hairdryer.

Do this with 2 or 3 tissues so that they’re ready for you in case you run out. Your hands may get messy, so it’ll be easier to have all your tissues ready. If you don’t have tissues, use toilet paper instead. Paper towels are not recommended because they are too stiff. Skip this step and the next for the Tim Curry version of Pennywise.

Start at the bottom edge of the bald cap and work your way up to the top-center of your forehead.

For best results, choose a wig with straight fibers, although a wig with wavy fibers may also work. Don’t use a curly wig. If you’re worried about the wig slipping back, apply some spirit gum to the underside of the wig’s hairline, then press it against the bald cap. If you are doing the Tim Curry version, use a straight, red wig instead. If you wish to use your own hair, comb it back, then spray your front hairline with white hairspray. [10] X Research source

Don’t worry too much about making it look neat. Pennywise doesn’t have nice hair.

For a smoother look, wait until the glue dries, then apply spirit gum over it. Only do this if you have spirit gum remover handy. A spoolie is essentially a mascara brush, but it comes with a longer handle, like a makeup brush. You can use an old, clean toothbrush instead.

If you are using water-based makeup, you’ll have to dampen the sponge first. You can use a spray-on foundation on your forehead and neck, but you shouldn’t use it on your face because it’s not precise enough. When doing your forehead, be sure to cover the bald cap too, all the way up to the wig.

This is mostly to set your “canvas. " You’ll be setting your makeup again at the end. “Baking” is a popular technique for applying setting powder, but you don’t need to do that for this stage. Save that technique for the end.

You can use a cream-based theatrical makeup or regular eyeshadow, like what you’d buy from the makeup counter. If you’re doing the 1990 version of Pennywise, apply blue eyeshadow over your eyelid in a triangle shape instead.

Take a moment to enhance the shadows you added around your mouth and under your eyes. This is only for the 2017 version, however.

Oil-based face paint will work the best for this, but you can use lipstick too. For a more accurate look, lightly brush or “feather” the red paint up the bridge of your nose by about 1⁄2 cm (0. 20 in). [29] X Research source If you want to do the Tim Curry version, pop on a rubber or latex clown nose. Do not use a foam clown nose; it’s too round.

For the Tim Curry Pennywise, make both the top and bottom lips just inside your natural lip line.

Pull out some reference photos of the 2017 version of Pennywise for this. If you’re doing the original 1990 Pennywise, draw a small, vertical black line under the center of each eye. They should only be about 1⁄4 to 1⁄2 in (0. 64 to 1. 27 cm) long.

Alternatively, apply a misting of setting spray instead. For best results, use theatrical-grade setting powder or setting spray. It will help your makeup last much longer!
