Sunglasses protect your eyes and make you look soo cool. Here’s an easy to remember rule of thumb for buying sunglasses for your face shape—buy the shape of the sunnies that’s opposite your face shape. In other words, if you have a heart-shaped or square face, buy round or cat’s eye glasses. Have an oblong shaped face, buy oversized frames, and if you have an oval-shaped face, lucky you, you can wear any style. Read Enter to Win Our Costa Rica Getaway! 1.
