How to put it together
- 1
Put on the black long-sleeve shirt and black leggings to create the dark, insect-like base body.
- 2
Step into the black boots or flat shoes.
- 3
Drape the red cloak or poncho over your shoulders, ensuring it covers your torso and hangs evenly.
- 4
Secure the cloak at the neck, adjusting the collar so it stands up slightly.

Put on the white horned mask, adjusting the strap so the black mesh eyeholes align with your eyes.

Hold the silver needle prop in one hand, ready to strike a dynamic warrior pose.
Makeup & hair
No makeup or hair styling is required, as the full-head white mask completely covers your face and hair. If your hair is long, tie it back in a low bun so it fits comfortably inside the mask.
