Smiski Costume
Bring the mysterious, glow-in-the-dark blind box toy to life.
Smiski are curious, minimalist Japanese blind box figures known for hiding in corners and glowing in the dark. Dressing up as a Smiski is a popular choice for fans of cute, quirky pop culture who want a funny, low-effort, or highly creative DIY look. The costume centers on a solid, pale green or glow-in-the-dark bodysuit paired with a matching full-face mask or hood.

How to put it together
- 1
Try on the light green morphsuit to ensure a snug, smooth fit.
- 2
If using glow-in-the-dark spray, hang the suit in a well-ventilated area and apply an even coat, letting it dry completely.
- 3
Prepare the hood or mask by ensuring the black felt eyes and mouth are securely attached in a simple, blank expression.
- 4
If making the blind box prop, cut armholes and a head hole in your painted cardboard box.
- 5
Step into the bodysuit, pull the hood over your head, and step into the optional cardboard box prop.
- 6
Strike a classic Smiski pose, such as peeking around a corner, sitting with your knees to your chest, or standing completely frozen.
Makeup & hair
Since the costume uses a full-coverage fabric hood or mask, hair should be slicked back or capped underneath. If you choose to leave your face exposed, apply pale green face paint and use black eyeliner to draw simple, solid black circle eyes and a tiny neutral line mouth.
