The Shade Of It All

Every face tells a story. And if our drag algebra --draggebra if you will--holds up, since shade derives from reading, the right pair of sunglasses equals fierce to the power of werq. Mathematics notwithstanding, finding the right pair of shades for your face can be a big brain teaser, but we've got you covered.

Here's a guide to make your search that much easier.

NEXT: Square Face

Square Face

With a strong jawline, prominent chin and a forehead on which you could project the widescreen version of Ben-Hur, your face is built like a tank. No need to go to war to find the right frames, though: A square face needs softer, rounded frames to accentuate those strong, angular lines.

NEXT: Round Face

Round Face

Your name may not be Alvin, but can we talk about those adorable chipmunk cheeks? Round faces may not be as angular or chintastic as the square face, but angular frames --square, rectangular, or wayfarer-- can add the facial definition nature denied you.

NEXT: Heart-Shaped Face

Heart-Shaped Face

There's a lot to love about a heart face --cheekbones from which the world hangs immediately come to mind-- but those wide temples and narrow chin can be tricky to style. Try aviator, rimless or round glasses, since they all elongate and balance out your features.

Oval Face

Lucky you, you're the type AB of faces: You can receive donations from any frame. Or maybe you're the type O --giving universal face. Either way, the sunglass world is your oyster, as pretty much everything looks good on you. So why not go for something a little more fun and daring?
