First of all, good question! Not all face shapes can go well with certain kinds of frames. Different people differ in their face shapes as well as in their suitable eyeglasses frames. As far as rectangular face is concerned, such kind of face is characterized by narrow shape that is longer than it is wide. High cheekbones, longer nose, tall forehead, and angular features are all highlighted. Since you have a rectangular face, it is better for you to try on some tall frames, which can help make your long face look shorter. You can also give it a shot at some sunglasses featuring broad frames, such as oversized or wraparound styles. Give any pair that complements your face shape a shot. You will find the perfect match.
