Polo Shirt

A polo shirt, also known as a golf shirt and tennis shirt, is a form of shirt with a collar, a placket with typically two or three buttons, and an optional pocket.

All three terms may be used interchangeably. Polo shirts are usually made of knitted cloth (rather than woven cloth), usually piqué cotton or, less commonly, interlock cotton, silk, merino wool, or synthetic fibers. A dress-length version of the shirt is called a polo dress.[1]
