CUSTOM SLIM FIT STRETCH MESH POLO SHIRT. 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.
