Blazer

English term. Precisely, it is a fabric with coloured vertical stripes or bands used for sportswear jackets, without turn-ups, characteristically worn by members of clubs or colleges. Today it refers to the classic men's dark blue jacket, which can be either single-breasted or double-breasted. Originally, the term defined a striped jacket, predominantly in a single-breasted style. The name comes from that of a warship, the H.M.S. Blazer, whose commander, in 1840, dressed the crew with white and blue vertical striped jackets. Since then, jackets used in sporting situations, especially nautical, were called blazers.
