dougi
A uniform for training, used in Japanese martial arts such as karate. This term is otherwise known as keikogi (keiko means practice, gi means dress or clothes).
The top part of the uniform is a jacket called uwagi, and is tied by a martial arts belt. The bottom part is a pair of pants called shitabaki.
In Korea, dougi are called dobok (도복), and are used for Korean martial arts such as taekwondo.
