 While simple clothing and equipment is still mandated at some levels of 4-H competition, in open competition and sanctioned events for various breeds, exhibitors usually follow the same style as seen in riding classes.Thus, it is common today to see Western-style exhibitors in very elaborate, appliqued ensembles bejeweled in swarovski crystals, showing horses in halters decorated with extensive amounts of sterling silver.The rules for showmanship classes are set by organizations such as 4-H, the United States Equestrian Federation and the American Quarter Horse Association.
