The Yi ethnic group has many branches, and the costumes vary greatly across different regions, with nearly a hundred types of differences, each unique and colorful. Women usually wear a large-sleeved, right-side opening top with embroidered or bordered edges, black headscarves, earrings, and silver flower brooches on their collars. Except for the Yi people in the Xiao Liangshan area who wear skirts, Yi women in other parts of Yunnan wear long pants. Many branches have exquisite floral borders on the hems of their pants. Married women also have beautifully colored floral borders on the collars, sleeves, and front of their clothes, especially the embroidery on their aprons is particularly dazzling. Unmarried girls in central and southern Yunnan often wear bright red "chicken cap" hats decorated with red tassels and beads. These chicken cap hats are usually made by cutting cloth into the shape of a rooster's comb and embellished with dozens, hundreds, or even thousands of silver buttons. The Yi people living in mountainous areas used to wear a "Cearwa" - a sheepskin cloak, which resembles a cloak, is woven from wool, reaches below the knees, and has woolen tassels at the bottom, generally in deep black. Before the age of 15, Yi girls wear red and white children's skirts and braid their hair into a single braid. At the age of 15, in some places, they hold an event called "Shalaluo", meaning "change skirt, braid two braids, pull out ear thread," indicating that the girl has grown up. After 15 years old, they wear long skirts with black middle sections, change their single braid to two braids, wear a headscarf embroidered with colorful flowers, and remove the old ear thread worn during childhood and replace it with shiny silver earrings. Yi men mostly wear black, narrow-sleeved, and bordered right-opening tops, and multi-pleated wide-legged long pants. They leave a small tuft of hair about three inches long on their heads, known as "Tianshabei" in Chinese, and "Zier" in the Yi language. This is a way for Yi men to show the divine, and it should never be touched. They wrap a long, green, blue, or black headscarf around their heads, and tie a long, thick cone-shaped "Zier" (called "hero's bun" in Chinese) in the front right corner. Men consider being clean-shaven beautiful; they pluck out all their facial hair during their spare time. They wear earrings with yellow or red beads strung with red silk threads, and the beads are adorned with red silk threads underneath.
