etymonline
corsage (n.)
late 15c., "size of the body" (a sense now obsolete), from Old French corsage "bust, trunk, body" (12c.), from cors "body," from Latin corpus "body" (from PIE root *kwrep- "body, form, appearance").
The meaning "body of a woman's dress, bodice" is from 1818 in fashion plates translated from French; by 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."
