Kids Ninja Costumes
MorphCostumes stocks kids ninja fancy dress in black-and-red warrior styles, hooded bodysuits and Lego Ninjago characters, sized Toddler (3-4 years) up to XL (12-14 years). Most sets pack the accessories in the photo, from a detachable face mask to foam throwing stars, so the costume works straight out of the box.

What to look for in a kids ninja costume
Ninja costumes get worn hard: running, hiding, jumping off the sofa. Size by height against the guide on each product page, not by clothing size, and go up where they fall between two: a tight hood ends the game early. Every costume goes through over 30 measurement checks by garment techs trained in tailoring, and all of our kids' products are safety tested by accredited labs.

Frequently asked questions
What age are kids ninja costumes suitable for?
Our range runs from Toddler sizes (around 3-4 years) up to Extra Large (12-14 years), so check the size guide against your child's height rather than their normal clothing size.
Do kids ninja costumes come with weapons or accessories?
Most do. Sets on this page include a face mask plus toy accessories such as foam throwing stars or plastic daggers, with the contents listed on each product page.
Are there ninja costume options for girls?
Yes. The dragon ninja costume above is cut for girls, a hooded tunic with a hand-printed dragon, and our black-and-red, black bodysuit and Ninjago styles suit girls and boys alike.
What is included in a Lego Ninjago costume?
The Lloyd Legacy costume comes with a foam tunic, half mask and Lego-style hands, in one size to fit up to 8 years; check each listing's includes section, since accessories vary between characters.
Can my child see and breathe properly in a ninja face mask?
Our detachable masks leave the mouth and nose clear, but vision through the eye holes is narrower than bare-faced, so keep an eye on your child around steps and kerbs, especially after dark.
How do I pick the right size ninja costume?
Measure your child's height and match it to the size guide on the product page rather than guessing from age alone, and size up if they fall between two sizes for a comfortable, active fit.
