The oxford shirt made its debut very early on in Ralph Lauren's designs, and since then it has solidified its status as a pillar of the Polo look. The fabric is developed with a secret wash that gives it instant character, ease, and a heathered softness-what Polo Ralph Lauren calls the perfect ""rumple."" The formula is so unique, it's been kept in a safe for more than three decades. Today, Mr. Lauren continues to create countless variations of his iconic shirt, including this gingham version that is finished with Ralph Lauren's signature embroidered Pony.
