Each frame is going to go with the frame of your face. So for instance, if you have a long oblong face you should consider checking out frames that have a low bridge which will shorten the frame of your face. Or if you have a round oval face, you might want to take a look at a few wholesale optical frames that have a walnut shape to them and that are wider than the widest part of the face. Shapes of frames also depend on other things as well besides the shape of the face such as the color of the eyes (secondary element in determining shape and color), hair, and skin (prime element in determining shape and color).
If you have darker skin or you have "warm" eye coloring such as blue or green you should consider circular or oval frames that are "warm" colors such as blue, green, orange, pink, etc. if you have lighter skin or more contrasting eye colors such as brown or dark green or blue you should consider optimal colors and shapes such as square frames and contrasting colors such as yellows and reds!
