Bijia

The bijia originated from a long-length Mongol vest.^{[1]: 46 [6]} According to the Yuan shi, the invention of bijiia is attributed to Empress Chabi during the Yuan dynasty.^[2][7] Empress Chabi designed the bijia so that it would be a convenient form of attire while riding horses and shooting arrows.^[2] The front region of the bijia designed by Empress Chabi was made of 1-piece of fabric, and its back region was twice longer than the front region.^[2][7][8] It was collarless and sleeveless, and there were two loop straps which attached to it.^[2][7][8] It also had no lapels.^[8] The bijia was first worn by the Yuan dynasty emperor but it later became popular among commoners.^[9]

After the fall of the Yuan dynasty, Mongol fashion of the Yuan dynasty continued to influence some styles of clothing worn in the Ming dynasty; this included the persisting usage of bijia.^{[1]: 46 [6]} The bijia became a type of women clothing in the Ming dynasty, and by the middle of the Ming dynasty it had become a favourite form of dress for women, especially young women.^[9]

In the Ming dynasty, the bijia was long in length and would reach below the knee level.^[3] It was embroidered on woven textile and a jade ornament would be attached at the front of the bijia as a front closure.^[3] Bijia created an illusion of slenderness, which women in the Ming dynasty sought after.^[3]

In the Qing dynasty, Han Chinese women were allowed to continue the Ming dynasty clothing customs.^[4] The bijia remained very popular in Qing dynasty,^[9] and it was one of the most common forms of female clothing worn in the 17th and 18th century.^[4]

The Chinese opera beixin (Chinese: 背心), also known as kanjian, majia, and beida, were sleeveless vests which originated from both the Ming dynasty's long-length bijia worn by women from the lower-middle class and from the Qing dynasty's majia (Chinese: 马甲),^[11] a type of vest which were worn by the Manchu.^[12]
