This elaborately detailed "Dandu Jacket" from the Guizhou region of southwest China features an intricate pattern of traditional spirals, scalloped edge designs, and symmetrical patterns on its shoulders and sleeves. It was worn as an everyday garment by women in the wealthier regions of Guizhou, signified by its fastening on the right side of the jacket. For festive dress, the jacket would fasten on the left.
