For Native American Heritage Month, one of the books I heavily relied upon for the research and documentation was this text, the Encyclopedia of American Indian Costume by Josephine Paterek. It's over 500 pages of documentation, photographs, and appendices that could tell you everything you would want to know about the styles of dress that Native Americans wore, how they were constructed, and how the materials used were gathered.
The tribes are categorized into geographical regions of the United States and even includes seperate sections for the California coast peoples, the Plateau, and the Sub-Arctic. From there the regions are broken up into entries for the predominate tribes that include traditional pre-contact dress and the transitional dress of the 18th-20th centuries. Within these well-sourced entries there are sections for women's and men's attire, makeup/body painting/tattoos, decoration, hairstyles, ceremonial dress, and accessories with appropriate photographs accompanying them.
