Plains men who had achieved honor were given the right to wear a highly decorated shirt. Created by women, these shirts are the crowning achievement of Plains Indian art. The body of the shirt was made from two animal hides, probably deer, and the beaded strips were added after the body of the shirt was created.This shirt was created on the Ft. Belknap Indian Reservation located in north central Montana; home of the A'aninin (Gros Ventre) and Nakoda (Assiniboine) tribes. When the tribes were put on the reservation in the latter half of the 19th century by the Federal Government, each tribe had its own unique tribal art style. Over time, these art styles merged to form a new style. The use of strong bright colors and an unusual use of color and designs are characteristics of the Ft. Belknap style.
