Aiming to produce the ideal knitted pique cotton tennis shirt, Ralph Lauren launched his first iteration in 1972. Today, Polo Ralph Lauren polo shirts are rooted in Ivy League aesthetics. Collared button-up shirts are complete with Polo Bear, Polo Pony and graphic embroideries, appearing in black, white and vivid colors. Striped designs are reminiscent of rugby shirts, with the brand’s T-shirts and Oxford shirts here.
