OVAL: This face shape generally has high check bones, medium wide foreheads, and a jawline neither prominent nor square. Features tend to be equally proportioned. Have this face shape? You have the advantage of looking nice in any sunglass shape: round, square, geomteric, conservative or avant garde.
ROUND: Do you have a rounded forehead and full cheeks curving gently into your chin and jawline? The contrast of large octagonal or square sunglasses will work will with your shape! Wraparounds also acheive a striking look.
HEART: In this case a relatively wide forehead and cheekbone area tapers into a narrow or pointed chin. Frames should feature oval lines at both top and bottom. To enhance the face, styles with the lower portion of the sunglasses that round outward will have a very nice effect.
SQUARE: This shape has the appearance of being squared of at the top and bottom with a wide forehead and a prominent square jawline. It often includes a short chin. Bold shapes which include rounded lesnes extending beyond the face are quite complimentary to the square face shape!
