A corsage is a small bunch of flowers a woman wears on a special day — a wedding, a formal dance, a graduation. It is pinned to her dress, often near the shoulder, or worn on the wrist with a band. It is not a big bouquet she carries in her hands; that is a bouquet. A man’s matching flower on a lapel is usually called a boutonniere, not a corsage, though people mix the two. The word is from French. Though actually, in French corsage first meant the body or bodice of a dress — the part that covers the torso — and only later the flowers worn there. English kept the flower sense. You mostly hear it around weddings and school formals; it is not an everyday object. In Taiwan you will more often hear the Chinese name than the English one.
