How to put it together
- 1
Put on the loose-fitting white karate pants.
- 2
Slip on the white gi jacket, wrapping the left side over the right side across your chest.
- 3
Secure the jacket by tying the inner and outer side ties if your gi has them.
- 4
Wrap the colored rank belt twice around your waist, centering it over the jacket, and tie it in a secure square knot at the front so the ends hang evenly.
- 5
Tie the fabric headband snugly around your forehead, knotting it at the back of your head.
- 6
Go barefoot or wear simple slip-on martial arts shoes to complete the authentic look.
Makeup & hair
Keep hair tied back securely in a ponytail or bun if it is long. Makeup should be minimal and natural, suggesting a clean, focused athletic appearance.
