CUSTOM SLIM, STRETCH MESH. An American style standard since 1972, the Polo shirt has been imitated but never matched. Over the decades, Ralph Lauren has reimagined his signature style in a wide array of colors and fits, yet all retain the quality and attention to detail of the iconic original. This version includes a hint of stretch, allowing for unparalleled ease of movement and comfort. At the placket, it is finished with genuine mother-of-pearl buttons.
