caparison (n.)

1570s, "cloth spread over a saddle," also "personal dress and ornaments," from French caparasson (15c., Modern French caparaçon), from Spanish caparazón, perhaps from augmentative of Old Provençal caparasso "a mantle with a hood," or Medieval Latin caparo, the name of a type of cape worn by women, literally "chaperon" (see chaperon (n.)). Past participle adjective caparisoned is attested from c. 1600, from a verb caparison (1590s), from French caparaçonner, from caparaçon.
