A bridle is equipment used to direct and control a horse. The bridle holds a bit which goes in the mouth of a horse, and has reins which are joined to the bit.
Bridles are usually made of leather. They are made of different parts which are buckled together. The headpiece, also called a crownpiece, goes behind the horse's ears. The browband is placed across the horse's forehead. Sometimes, a strap called a martingale is attached to the noseband.
