PRODUCT DETAILS
Picture this: your child walks into the classroom on Book Week morning dressed as a full-on ninja warrior - black jumpsuit with dramatic red trim, hood pulled up, ninja star at the waist. The stealth entrance? Already legendary. This Kids Ninja Costume is the complete package: structured shoulder cape, face-covering hood, red obi belt with emblem, plus matching arm and leg wraps that look like proper warrior gear.
What's in the Box
- Black ninja jumpsuit with attached shoulder cape panels
- Pullover hood with face opening
- Red obi-style belt with ninja star emblem
- Red arm wraps (pair)
- Red leg wraps (pair)
Perfect for Book Week martial arts characters, school dress-up days, or any kid who wants to channel their inner warrior. The lightweight fabric moves with them (crucial for recess ninja moves), and the red accents pop against the black - great for kindy photos and classroom parades. Pairs with any action-hero book for Book Week, from comic-book adventures to mythology tales with warrior characters.
Parent FAQs
What size should I order?
The jumpsuit runs true to size with a bit of stretch through the body. If your child is between sizes or on the taller side, we'd say size up - the elastic at wrists and ankles will keep everything snug even if there's extra length. 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 like a onesie - it's not bulky enough to layer over a full outfit. Pop a black long-sleeve shirt and leggings underneath if the classroom runs cold, and the costume will still sit neatly.
Care: Hand wash in cold water, hang to dry. Keep the belt emblem away from heat to protect the detail.
