Ninja Costumes for Adults and Kids

Ninja costume styles for adults and kids

The adult ninja costume here is a hooded jumpsuit, with the mask as its own separate piece rather than part of the hood, so it comes off between photos. The samurai pick breaks that pattern, robe and armour over the top instead of black stealth. Younger ninjas with their own dedicated range are on our kids' ninja costumes page; the samurai-style pick below sits closer to our historical costumes range if that's more the look you're after.

The Mens Samurai Warrior Costume takes the armour route rather than the stealth one: a blue robe, red armour piece, yellow rope belt and horned hat, sized M to XL (97 to 122cm chest).

The Womens Ninja Costume Black/Red layers a separate red top over the hooded jumpsuit and adds arm warmers, a mask and a toy dagger, sized S to XL (US 4-6 to US 16-18).

Foam rather than fabric on the chest, the Kids Lego Ninjago Lloyd Legacy Basic Costume is a tunic, mask and hand set that fits up to 8 years old, for the child who already knows Lloyd by name.

The Kids Black And Red Deadly Ninja Costume pads the chest out into a muscle bodysuit, with an attached belt, detachable mask and weapon accessories, sized 4-6 up to 12-14 years.

What to look for in a ninja costume

The four picks above run on different sizing bases, so check which one applies before ordering: the women's style sizes in US sizing, the samurai costume by chest measurement in centimetres, and the kids' costumes by age. All four are 100% polyester, which is why they take a cold hand wash and an air dry and none of them are machine washable; a hot machine cycle is what takes the print and the stretch out of them. Any toy dagger, sword or accessory in the box is a plastic prop rather than a real blade, and all of our kids' products are safety tested by accredited labs, but we would still keep an adult supervising younger ninjas playing with them.

Frequently asked questions

What size ninja costume should I get?

Check which sizing basis the costume you want actually uses first: the women's ninja costume sizes in US sizing (S to XL), the samurai costume by chest measurement in centimetres (M to XL), and the kids' costumes by age. Each product page carries its own size guide, so measure before you order rather than going by a usual clothing size.

Is a ninja costume only for Halloween?

No. World Book Day, birthday parties, cosplay meet-ups and martial-arts club socials all call for one, and our ninja range is stocked and sized for wear right through the year. A cold hand wash and an air dry rather than a machine cycle is what gets one to the next occasion intact.

Are the toy weapons that come with a ninja costume safe for kids?

The daggers and swords included are plastic props, not real blades, and all of our kids' products are safety tested by accredited labs. That said, they're still a prop with a point on the end, so we'd keep an eye on younger children while they're playing with one.

What's the difference between a ninja costume and a samurai costume?

A ninja costume is built around stealth: a close-fitting hooded suit or jumpsuit in black or a dark print. A samurai costume is armour-led instead, like our Mens Samurai Warrior Costume above, with a robe and armour piece over the top. They size differently too: our women's ninja costume runs in US sizing, the samurai costume by chest measurement in centimetres.

Do you have ninja costumes for kids as well as adults?

Yes. Two of the four picks above are kids' costumes, sized by age rather than clothing size, and our wider kids' ninja costumes range, linked at the top of this page, carries more designs in the same age bands.
