The qujupao is a style of hanfu that was worn as informal wear during the Spring & Autumn Period, Warring States, Qin, and Han Dynasties. It's construction is that of a long wrap-around robe with a y-shaped collar and a sash around the waist or hips. Its hem is curved, this detail distinguishes it from the zhijupao, which has a straight hem. These two styles are reffered to as "shenyi" and could be worn by any gender.
Shenyi could be confused to be kimono, but shenyi is really the predecessor to kimono, which it was influenced by.
