Wrestling suits vary depending on the wrestling program. For example, Mongolian wrestling wears a leather sleeveless blouse, which is not tied, belted, trousers, or knee pads. Judo and karate are worn in traditional Chinese white slanted blouses, and under the knees, the belts are worn. Countries such as Japan also distinguish judo grades by belt color. The sumo is used to naked body, and the armpit is only a narrow strip of cloth and a belt.
