Sport coat

A sport coat, also called a sport jacket (or sports coat or sports jacket in American English), is a men's smart casual lounge jacket designed to be worn on its own without matching trousers, traditionally for sporting purposes. Styles, fabrics, colours and patterns are more varied than in most suits; sturdier and thicker fabrics are commonly used, such as corduroy, suede, denim, leather, and tweed.

Originally, sports coats were worn as appropriate attire for participating in certain outdoor sports. With time, they were adopted by those attending such events, and came to be used on more formal occasions, sometimes being used in school uniforms.^{[citation needed]}
