A notable feature of Mongolian costumes is Tibetan style, that is, in addition to some important festivals and gatherings of some Mongolians in some areas, there are more costumes with Tibetan costume elements. Perhaps this is the result of the long-term mutual blending and coexistence of many ethnic groups, which is recorded in Haixi Prefecture Records and Henan County Records. Dai costumes not only give people a strong sense of beauty, but also have a strong national style. The men's clothes in Dai costumes are simple and generous, including collarless double-breasted or large-breasted small sleeve tops, plain trousers and white and cyan cloth heads. This kind of clothing is light and comfortable in farming and makes the wearer look handsome in dancing. Dai women's costumes are colorful, which fully shows their vitality and sexiness. Dai women wear all kinds of tight underwear, light-colored long-breasted or double-breasted narrow-sleeved shirts, and colorful skirts with various patterns. Dai women like to tie their long hair in a bun, insert combs obliquely on it, use hairpin or flowers as decorations, and wear gold and silver ornaments and tie a delicate silver belt around their waists. Such clothes dress them up beautifully and elegantly. They are like beautiful peacocks, elegant and demure.
