The Yi costumes are varied and colorful, which are the concrete embodiment of the traditional culture and aesthetic consciousness of the Yi people. They are mainly divided into men's and women's costumes. Butuo Yi men like to wrap their heads with blue silk or cotton scarves, which are called "Eti" in Yi language. They are about 1 foot wide and 30 to 40 feet long. They are wrapped around their heads and their hair is wrapped in the scarves. The tops are tight-fitting single clothes made of silk or cotton, mostly black or blue, with narrow sleeves, high waist, and embroidered patterns on the front, back of the neck, and cuffs. The collar and right lapel are decorated with nine rows of long silver or copper buttons. Most men's trousers are made of blue or blue cloth, which are characterized by deep crotch, large waist, and narrow trouser legs. The belts are generally made of sky blue or grass green cotton cloth, hollow in the middle, and can be used as pockets. In winter, they wear sheepskin felt, wool felt or "Charwa" on the outside. Middle-aged men and children also hang "hero belts" on their shoulders during festivals. Butuo Yi women all wear pleated skirts and long coats. Before changing skirts, girls' skirts are tube-shaped, woven with red and white wool or cotton threads, with the lower end folded into pleats with green, white or blue cloth, and trimmed with red and black cloth strips; young women wear red and black pleated skirts; middle-aged and elderly women wear blue, green cloth pleated skirts or black wool pleated skirts. Young women wear hats or "Happa"; middle-aged and elderly women wear "Eshuo". Generally, they wear "Happo" or "Haboleding" on the outside.
