A long-sleeved knit shirt, often with bold horizontal stripes in two alternating colours, that has a white knit collar and a button-down placket neckline. The sport of rugby was founded in the 1820s at Rugby High School, in England. Some fifty years later, the sport became so popular in private academies and universities that leagues formed, and the development of the shirt with distinctive school colours began to unfold. Today, the rugby is a casual wear staple, offering both men and women this athletic classic for everyday use.
