All over the the world, special occasions require special clothing and the Maya are no exception. Many of the rites of passage, particularly baptisms, weddings, and funerals, require clothing styles that are specific to that event. More generally, though, fiestas require that attendees wear special clothing. Sometimes this special clothing is easy for even outsiders to recognize: masks worn for dances at fiestas, elaborate costumes worn during mock tiger fights, clothing worn by young girls in Ascension Day processions to illustrate the life of the Virgin Mary. In other cases, fiesta clothing may by differentiated by subtleties in weaving technique or type of material used. In some communities brown cotton, as opposed to the more plentiful and easier to weave white cotton, indicates that a huipil is for ceremonial use only.
