A Bridle in Pony Play is a head harness modelled on equestrian tack. It commonly comprises head, cheek and brow straps and points of attachment for a Bit, Reins and sometimes Blinkers. Bridles vary from lightweight ornamental designs to substantial leather constructions.

The Pony Play Bridle adapts real-world equestrian gear, with dedicated makers producing designs suited to human wearers.

Bridle design, fit and comfort require attention. Communities generally treat bridle fit as a matter of both safety and welfare.
