Nothing spruces up a summer outfit like the perfect pair of sunglasses. Charming Charlie made this infographic as a how-to guide on how to find the best frame for your face shape. The guide begins by illustrating the different types of face shapes: round, heart, square and oval, with a description of the features that usually make up each. It then provides suggestions on the best type of frames to fit each respective face shape. It goes on to provide additional tips on how to find frames that best match your skin tone, and explains how to determine your skin tone if you are unsure. Finally, the guide provides some suggestions on how to select the right tint for you.
