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. This fabric has been developed with a secret wash that gives it instant character, ease, and a heathered softness. The formula is so unique, it's been kept in a safe for more than three decades. In addition to details that evoke its prep-school inspiration, it offers a relaxed feel that produces what they call the perfect rumple.
