Jinbei
A jinbei (甚平) (alternately jinbē (甚兵衛) or hippari (ひっぱり)) is a traditional set of Japanese clothing worn by men, women and children during summer as loungewear. Consisting of a side-tying, tube-sleeved kimono-style top and a pair of trousers, jinbei were originally menswear only, although in recent years women's jinbei have become popular.
