Choosing a haircut for your face shape can be a challenge - particularly because you don't quite know what you're buying until you've already bought it - but sunglasses offer a whole different set of shopping parameters. Most importantly, you can see what you're getting before you buy. To help steer you towards the perfect pair, below are some guidelines for finding sunglasses that tend to flatter four common face shapes.
Face Shape: Oblong
Frames to try: Round or Square.
Frames that are the same length vertically as horizontally will cover a good portion of your face and give the illusion that it's shorter.

Choosing a frame shape that contrasts with the lines of your face will soften an angular jawline and hairline, creating a more proportioned silhouette.

Face Shape: Round
Frames to try: Rectangular.
The angles will downplay your face's roundness and make it appear longer.

Face Shape: Heart-Shaped
Frames to try: Rimless or Aviator.
They'll accent your eyes and play down the angles on the lower half of your face. Colored lenses will draw even more attention towards the eye area.
