Heart-Shaped Faces — Aviators and Rimless Styles
Aviators are good for balancing out a broader forehead with a narrower jaw line and a more pointed chin, because of the way they flare out at the bottom. Rimless styles are also good, because they keep the face from looking too top-heavy.
Square-Shaped Faces — Ovals and Rounded Rectangles
Narrower oval and rectangular styles with rounded edges are great for softening a strong, square jaw and lengthening the face.
Narrow Faces — Taller Frames and Decorative Temples
Try taller, squared-off or more circular frames, which will take up more room on your face and help balance out your features better than oval or rectangular frames. Also look for glasses with thicker arms or decorative details at the temples, since they will draw attention to the sides of your face and make it appear broader.
Round Faces — Rectangular Frames and Contrast Bridges
Angular, rectangular frames help elongate the face and a contrasting bridge makes the eyes look farther apart.
Trapezoidal Faces — Half-Rim and Cat Eye Shapes
Try a half-rim style or a dramatic cat eye to bring attention up and balance out your jaw line
Oval Faces – Top-Heavy Frames and Butterfly Shapes
If you've got broad cheek bones, but a narrower forehead and chin, look for styles that are thicker or darker on the top than the bottom, or try a butterfly style, which wings up and out slightly at the top.
