How to Make a Ninja Costume

Co-authored by Amber Crain

Last Updated: June 4, 2024

A ninja outfit should be dark, concealing and comfortable – the better to execute your ninja moves. You can make a no-sew ninja costume out of a black turtleneck, black cargo pants and a thin black robe. You’ll also need a black scarf, black ribbon, black boots, a long-sleeved black t-shirt and black gloves. Grab four red or black t-shirts to create the pant guards, plus a few ninja accessories like fake throwing stars, and your ninja costume will be good to go!

Creating the Ninja Top and Pants

1
Tuck a black turtleneck into a pair of black cargo pants. Slip into a long-sleeved black turtleneck shirt. Pull on a pair of straight-fit cargo pants that are slightly loose.
- If you don’t have a black turtleneck, a white one will work. Make sure you change the other main costume details to white, as well.
- If you don’t have black cargo pants, try black tights, skinny jeans or leggings.
All cargo pants are straight-fit, but ninja pants taper at the ankles. To get the same effect, use black ribbon to tie the pants off just above the ankles. Tie the knots securely.

Obtain a black kimono or short black robe. A real kimono might be expensive, but the perfect substitute is a short black satin (or thin cotton) robe. These can be found at any department store. Make sure it comes with a belt!
- If you can’t find a completely black satin robe, look for one that has detailing in bright, rich colors like red, blue, green and white. Minimal floral detail in those colors would work, for example.
- You could also just get the darkest solid color they have (red and white ninjas aren’t uncommon).
Slip it on like you would a regular robe, then arrange it until you feel comfortable. Fasten the belt firmly at the waist by tying it in a knot.
Any material will do – leather, wool, knit – as long as they’re black. Tuck the wrist part of each glove into the sleeves of your black turtleneck.

Wrap a black scarf around your upper torso. Once you get it around your upper torso (bottom half of your ribcage down to about your belly button), the front will look like a very wide belt. Take the ends of the scarf and tie them together tightly behind you. Use safety pins to secure the scarf in place.
- For a cleaner look, tuck the ends underneath the main part of the belt so they don't hang down.
Slip on a pair of black boots. Before you tie them, tuck the ends of your pants down into them. Then tie them like you normally would, securing the pants in place.

In other words, pop your head about halfway through the collar. The top of the tee (the collar) should be resting on the arch of your nose and ears.^{[1]

Adjust it so it's a bit above your eyebrows. It doesn't have to feel tight just yet, just get it situated in place.^{[2]

Tuck the material under itself so that it just covers your forehead. It's okay to leave the sleeves dangling in the back. You can either leave them free or tuck them into the turtleneck.^{[3]

Pant guards are tied around both calves and around both thighs, right above the knees. You’ll need four shirts. You could also use scarves instead of t-shirts, if you have those on hand. Red and black are ideal, but white would work, too.

Place one shirt across your upper thigh above the knee. The collar should be pointing toward your navel at an angle. Tuck in the seam of the collar to get rid of the awkward lines. Tuck any loose material so that the band is 2–3 inches (5.1–7.6 cm) wide.
- Your thigh is not in the t-shirt. The t-shirt is simply draped over it.

Take the sleeves and wrap the shirt around your upper leg. Tie off the sleeves in the back of your leg. Fold the knots under. Tuck any loose material so that the band is 2–3 inches (5.1–7.6 cm) wide.
- Then, tie off the bottom ends of the shirt behind your leg. Make sure you tuck loose ends or knots. Do this to both legs.
Wrap a t-shirt around the middle of one of your calves. Tie the sleeves in the back, just like you did with the thigh guards. Fold the knots under the fabric. Do the same thing for your other calf.
You could make throwing stars or a ninja sword out of cardboard, or buy plastic ones from a costume shop and carry those. If you have nun-chucks, carry those with you. If nothing else, ninjas used long wooden staffs as weapons, so you could try using the long handle of a broom or find a tree branch outside that resembles a staff.
Take a piece of cardboard, and cut it to the shape of the weapon. Use duct tape, to create a sliver shine. On the end, take black tape, or cloth for the handle.

Question

Why does a ninja need weapons?

Community Answer

If you are going full ninja, then you might use them against enemies if the need arises. Strictly in terms of the customs, though? It is simply to finalize the stereotypical ninja look.

What can be a substitute for black boots?

You can just use some black sandals instead. The stereotypical ninja wears sandals also.

Make sure to tuck in any loose hanging ends. If something keeps popping out, grab a safety pin to ensure it doesn't keep happening.

Be careful not to tie the shirts too tightly to avoid reducing circulation.

Be sure to wear appropriate shoes with your ninja costume—not flip-flops or slippers. To capture the stealth spirit of a ninja, try not to make noise while you're moving around.
Make sure that your weapon clearly looks fake, especially if you're wearing your costume out in public. If your weapon looks too real, law enforcement might get suspicious.
