Caparison.
Synonyms:
accouterments, harness, housings, trappings.
Harness was formerly used of the armor of a knight as well as of a horse; it is now used almost exclusively of the straps and appurtenances worn by a horse when attached to a vehicle; the animal is said to be "kind in harness." The other words apply to the ornamental outfit of a horse, especially under saddle. We speak also of the accouterments of a soldier. Caparison is used rarely and somewhat slightingly, and trappings quite contemptuously, for showy human apparel. Compare ARMS; DRESS.
