corsage (n.)
late 15c., "size of the body," from Old French cors "body" (see corpse); the meaning "body of a woman's dress, bodice" is from 1818 in fashion plates translated from French; 1843 in a clearly English context. Sense of "a bouquet worn on the bodice" is 1911, American English, apparently from French bouquet de corsage "bouquet of the bodice."
