Breechclout.
—The breechclout is the only undergarment worn by the men, both in everyday life and in ceremonies. It is used to protect the person even when trousers are worn. It is always worn under the dance kilt except by the Mudheads, the Zuñi clowns, who are "just like children"[22] and are symbolized in myth as supernaturals "in semblance of males, yet like boys, the fruit of sex ... not in them."[23]
The size of the breechclout varies. In Taos it is broad and long, hanging
nearly to the ground,[24] while in the west it is short and narrow, the ends merely folding over the belt, front and back. The most desired material for this garment is hand-woven cotton cloth, but dark blue native cloth is often used, and sometimes even the woven ceremonial sash itself is used, its gay-hued ends contributing greatly to the color of figure and dance.[25]
The ordinary breechclout often has fringed ends or ends finished with embroidery or bright cording in geometric patterns. Decorated ends form a design element in the costume when drawn out over the belt and allowed to hang free (pl. 35).
