Riders must wear a long-sleeved shirt, jeans, and cowboy boots. In most competitions, they also wear chaps. Gloves are optional. There has historically been less difference between men's and women's attire in reining than in most western events, though women's clothing is more influenced by fashion trends from Western pleasure competition, and thus women sometimes wear brighter colors, and are more apt to add a decorated jacket or vest, though usually not as flashy as in other horse show events. Wearing a certified equestrian helmet is permitted by some organizations, though not commonly used.
