Yīcháng (衣裳)
Yichang is a generic term for a style of clothing consisting of an upper garment, the yi, and a lower garment, the chang. Most commonly, the upper garment would be a cross-collared top and the lower garment would be a skirt (qun) or trousers (ku/kun). The division of the upper and lower garment was considered symbolically important, as a representation of the greater order of the heavens and the earth. The traditional sensibility was that a woman’s upper garment should end around her waist with her lower garment meeting the top, to show the earth supports the heavens; whereas a man’s upper garment should extend long enough to partially cover his lower garments, to show the heavens embrace the earth.
The particular styles of the yichang upper and lower garments varied greatly throughout history. In the Shang Dynasty, the yi was worn over the chang and tied with a sash. In the Qin and Han Dynasties, women began to wear the chang over the yi. Sleeve depth and yi length trends would also evolve throughout history. For instance, in the Shang Dynasty, the yi featured narrow sleeves and a tunic-length hem; whereas in the Northern & Souther Dynasties period, women favored deep sleeves trailing to the knee and a shorter top. Chang length would also vary from knee-length to trailing on the ground, largely as a measure of status since workers needed their clothing to not obstruct their work whereas nobility could afford to wear impractical garments. Despite its many changes in form, the basic yichang silhouette was worn from the Shang Dynasty through the Song Dynasty. Most styles of yichang have been unisex, however styles like qixiong ruqun and aoqun were only worn by women.
