When it comes to choosing sunglasses, the options are endless, but that doesn’t mean they’re always right. Choosing sunglasses based on your face shape will help you know which style is the most flattering for you.

First things first: how do you identify your face shape?

Stand in front of your mirror and using lipstick (or any non-permanent marker), draw the outline of your face, leaving out your ears. This will help you determine whether your face is heart shaped, oval, oblong, round or square.

Heart-shaped faces are known for their wide foreheads, sculpted cheekbones and pointy chins. Oblong-shaped faces are known for their linear curve from jawline to long chin. Round-shaped have foreheads that fall in line with their jawline and a slightly smaller chin, and oval faces are known for their perfectly balanced forehead and jawlines.

Now that you’ve determined your face shape, let’s get down to business!

Heart: How do you draw attention away from your wide forehead and to your gorgeous cheekbones instead? Sassy cat-eye frames! Not many people can carry off exaggerated tips that cat-eye frames offer, but you can! Try pairing this look with a fun and loose French twist and red lipstick, you’ll get everybody talking!

Oval: Make the best of your easily complemented face shape and invest in a pair of this season’s trendiest eye-frame shape: the over-sized wayfarer. This frame doesn’t really work on heart-shaped or oblong faces because of their proportions, but you can carry off this style the best of all. Make them envy you at the next pool party with your hip wayfarers paired with a beachy, fishtail braid and nude lipstick.

Oblong: Exaggerated, square shaped frames work best on you, so go ahead and pull a Jackie O. and invest in some chic, glossy black square shaped frames. Style your hair in loose, glossy waves and wear a coral lipstick, everyone will wonder who the celebrity is at your next soirée.

Round: Your delicate proportions will look fantastic in a stunning pair of small, square shaped frames. The square frames will help break away the monotony of your face shape and add a unique element to your look. These frames would look great with your hair in a short bob with wispy bangs.

Square: Not a lot of people can pull of aviator shades, but you can! Make everyone know you mean business by investing in a pair of wire-framed aviator sunglasses with round lenses. Pair this style with long wavy hair and a busted denim jacket for added effect.
