Originated in the Qin dynasty (221-202 BC), crotchless trousers are a type of apparel that stretches from above knees to ankles with the hips and outer sides of the thigh exposed. Worn by both men and women, such a kind of garment usually went with the regular trousers with crotch, serving as both cover and ornament, similar to the function of the present-day oversleeves. Such a design, which was also seen during the later the Song (960-1279 AD) and the Ming dynasty (1368-1644 AD), reached popularity in the Qing dynasty (1644-1911 AD). As stated in the book Classified Notes of Qing-Dynasty Unofficial Historical Material (Qing Bai Lei Chao, 清稗类钞), crotchless trousers, with a triangular upper half and a rectangular lower half (on each of the trousers legs), are usually worn outside padded, lined or unlined pants.
