Your kid walks into the classroom on Book Week morning as a full-on ninja warrior — royal blue jumpsuit with printed armor plating, orange cross-body harness, weapon pouches at the belt, and a mask with angry eyebrows that means business. The other kids are going to lose it. This Kids Blue Ninja Warrior Costume brings martial arts hero energy without the sewing machine. Stretchy polyester jumpsuit with satin-like sheen features trompe-l'oeil armor details printed right on (no fiddly separate pieces to lose), plus a fabric belt that ties at the waist and a matching hood-mask for full ninja stealth mode.

What's in the Box

Royal blue jumpsuit with printed orange harness, belt, knee pads and armor panels (back zip closure)

Perfect for Book Week (pairs with any martial arts or warrior hero theme), school dress-up days, Halloween, costume parties, or just backyard ninja training sessions. The stretchy knit fabric moves with your kid — no stiff costume restricting cartwheels or dramatic fight scenes. Printed details mean everything stays put through active play, no Velcro tabs falling off mid-mission.

Parent FAQs

What size should I order?

The jumpsuit runs true to size with plenty of stretch through the body. If your kid is between sizes or tall for their age, we'd say size up — the cuffs are elasticated so you won't get bunching at the ankles. Returns are easy if the fit's not right.

Can they wear this over regular clothes?

The jumpsuit is designed to go on over underwear (not bulky layers). Stretchy fabric gives a sleek ninja silhouette. On colder Book Week mornings, a thin long-sleeve tee underneath works fine — just avoid chunky jumpers or the back zip gets tricky.

Care: Hand wash cold, hang to dry. The printed details are heat-set but we'd keep the iron away to be safe.
