Whether worn while lounging poolside or dodging paparazzi flashbulbs, cat eye shades are a foolproof path to retro-chic. Pair with your favorite Old-Hollywood staples (wide brimmed hats and glossy curls, anyone?) for a look that screams coquettish starlet. But with eyes this stylish, beware: other jealous admirers might get a little catty!
