Dressage is an event where horses do not jump, but must be very obedient to their riders. There is usually a sequence that the horse and rider must complete. Letters are placed around an arena to show where movements should happen. In dressage the horse and rider can also perform a freestyle, which is also known as "Dancing on Horseback". Dressage riders usually wear tight pants called breeches, as well as a blouse, a top coat and a top hat. The moves of the horse are very graceful and people like to watch them. Horses that compete at the Olympics in dressage have had many years of training to learn all the moves they must do for the competition.
