If you have a round face you should look for rectangular or squarish frames. Oval shaped faces are blessed with the ability to rock the majority of frames, especially square. Triangular-shaped faces should gear towards straight, flat top lines or cat-eyed frames with color. For those of you with inverted triangular-shaped faces, rimless frames and light colors is the way to go. If you have a square or diamond-shaped face, oval frames would suit you best that are rimless.
