Taiwanese Indigenous people's clothing has evolved from square-styled upper garments in the early days to long upper garments with long sleeves in the contemporary era. However, detailed historical documents and images of such clothing (including clothing over the past two centuries) remain scant except for those found in the collection of six indigenous peoples' museums in Taiwan. Thus, the National Palace Museum (NPM) Southern Branch brought said museums together, hosting a joint exhibition displaying Taiwan's indigenous textiles. The aforementioned museums included the National Taiwan museum, National Taiwan University Museum of Anthropology, National Museum of Prehistory, Museum of Institute of Ethnology, Shung Ye Museum of Formosan Aborigines, and Beitou Museum. A brief description of the six museums is provided as follows: (a) the National Taiwan Museum and National Taiwan University Museum of Anthropology possess rare embroidery and weaved cotton clothing of plains indigenous peoples; (b) the National Museum of Prehistory has thoroughly studied the history of indigenous people on Taiwan's east coast and preserved their culture; (c) the Museum of Institute of Ethnology has actively researched indigenous people and collected related artifacts since 1945, forming a solid research foundation; and (d) the Shung Ye Museum of Formosan Aborigines and Beitou Museum boast over thousands of indigenous people's clothing, enriching their culture. By working with the six museums, the NPM enables inter-museum resource exchanges, research integration, and the cohosting of exhibitions. By exhibiting more than 200 pieces of classic costumes, the NPM and museums allow audiences to see the sophisticated craftsmanship and living aesthetics of indigenous peoples, cultural integration between different regions, the interaction between traditional and modern elements, and the cultural environments of Taiwan as an island in Southeast Asia.
