A polo shirt (also known as a tennis shirt or golf shirt) is an informal shirt featuring a collar, placket neckline, and two or three buttons. Polo shirts are usually short sleeved, plain, and without a breast pocket. It could be said that a polo shirt is midway point between a t-shirt and a dress shirt with its medium-weight (often brightly coloured) fabric being more akin to a t-shirt, yet its collar bearing more resemblance to a dress shirt. More often than not, a polo shirt with have logo embroidered on the left side of the chest, this is for branding and aesthetic purposes.
