The oxford shirt made its debut at the beginning of the Polo Ralph Lauren brand, and since then has solidified its status as a pillar of the Polo look. Today, Mr. Lauren continues to design countless variations of his iconic shirt, including this relaxed version that is finished with Polo Ralph Lauren's multicolored signature Pony. A multistep process that includes high-tension yarn-spinning gives this shirt's pure cotton poplin a dose of stretch for ease of movement.
