What the dancers wear are not costumes, for a costume represents something that is not the reality of the person wearing it. Point made and taken. Now tell me something about the regalia. Among the women, look for traditonal, fancy, and jingle dancers. Traditional men's and women's dress is reflective of the traditions, achievements, or clan associations of the dancer.
Fancy dancers make use of bright colors, as well as more modern materials, patterns and motifs.
Among the women, look for bright colors and lots of fringe. Grass dancers' regalia is characterized by long, thick fringe all over the body, while women's jingle dresses are covered with sewn-on wrapped tin cones that jingle in time with every step and movement. To the newcomer, the dances may seem similar, but each classification of dancers has a certain set of steps and variations that are consistent with the classification. Tell me about the Grand Entry. Typically there is a Grand Entry in the early afternoon and one for the evening dancing.
