When it comes to shape, remember that opposites attract. The shape of the frame should contrast with the shape of your face. For example, if you have rounder features, more angular glasses will suit you best.Your frames should be in proportion with the rest of your face. This is different for sunglasses, which tend to be larger for greater coverage and protection.Most wearers choose a color that complements their skin tone, eyes and hair. Glasses that contrast with your personal coloring will make a bigger statement.
