This article mainly discusses the basis, content, and path of the integration and mutual learning of ethnic costume culture in central Yunnan, and explores the interaction between traditional ethnic social costume culture and contemporary culture, so as to establish the significance of cultural mutual learning and integration for the protection and development of traditional culture. In the process of changes in social forms and times since modern times, ethnic costumes in central Yunnan are based on the humanistic ecological environment of ethnic interweaving and the common genes of traditional Chinese costume culture. They are integrated and mutually learned in five levels: materials, styles, techniques, aesthetic interests, and ideological connotations. The costume culture of various ethnic groups spontaneously spreads and shares through cultural dissemination and mutual benefit, and then integrates into the innovative, creative, and revenue generating costume culture industry of the current era under the promotion of national administrative power. It is also a visible, enjoyable, and participatory public culture of the current era, and a creative response to the current social and cultural situation through the sustainable development of costume culture.
