Ninja Costume
Blend into the shadows with an authentic, stealthy shinobi look.
The ninja, or shinobi, is a legendary shadow warrior of feudal Japan, widely chosen for Halloween and cosplay due to its sleek, mysterious aesthetic [1.2.8]. This classic look consists of a loose-fitting black wrap top, matching pants, arm gauntlets, a waist sash, and a face-concealing hood. With the right accessories, you can easily customize this outfit from a historical spy to a modern action hero.

How to put it together
- 1
Put on the black jogger pants and the black wrap jacket, crossing the left side over the right and securing any ties.
- 2
Tie the wide black sash firmly around your waist to keep the jacket closed and provide a place to tuck your prop weapons.
- 3
Slide on the arm gauntlets or wrap black fabric strips around your forearms to secure the loose sleeves of the jacket.
- 4
Pull the black hood over your head, then tie the face mask across your nose and mouth, leaving only your eyes visible.
- 5
Tuck your toy katana sword into the waist sash on your hip or strap its sheath across your back.
- 6
Carry your prop throwing stars or kunai knives in your hands or tuck them securely into your belt.
Makeup & hair
Since the hood and mask cover almost your entire head, hair should be tied back flat against your head. Focus on the eyes by applying dark eyeliner or smoky eyeshadow to make your gaze pop from behind the mask.
