The keyhole style frame is becoming more and more popular as the seasons go on, so being the nice guys that we are, we're going to give you a heads up on the only pair you'll need this summer. The retro silhouette from Ralph Lauren Purple Label looks so good in all three colorways (tortoise, black, and dark green), so choosing which one should be the only question. Another plus is the minimal branding on the lens that you won't find on every other pair of shades you want. For $375, it's worth every penny. Cop a pair now online and at Ralph Lauren retailers.
