Judogi

Judogi (柔道着 or 柔道衣) is the formal Japanese name for the traditional uniform used for Judo practice and competition.
A judogi is somewhat similar to a karategi (空手着 or 空手衣, Karate uniform) as it shares a common origin. Jigoro Kano derived the original Judogi from the Kimono and other Japanese garments around the turn of the 20th century, and, as such, the judogi was the first modern martial-arts-training uniform. Over the years, the sleeves and pants have been lengthened, the material and fit have changed, the traditional unbleached cotton is now a bleached white, and blue Judogi have become available; nevertheless, the uniform is still very close to that used 100 years ago. Other martial arts, notably Karate, later adopted the style of training uniform that is used in Judo.
