The Native American bustle is a traditional part of a man's regalia worn during a dance exhibition or wachipi (pow wow) and originates from the Plains region of the United States. In its modern form, the men's bustle is typically made of a string of eagle or hawk feathers attached to a backboard. Eagle and hawk feathers are sacred religious objects to Native American people and the possession of eagle and hawk feathers are protected by the eagle feather law (50 CFR 22).
