(InStyle.com) -- Not many things that truly protect your health can also claim to be sexy, cool, seductive and alluring (not to mention up your mystery factor). Read on for the best frames to flatter your face shape, plus get tips on which glasses will best complement your nose size, eyebrows and skin tone.
If your face is round
Wide ovals and sleek cat's-eye styles work to diminish fullness. Look for frame styles that are wider than they are tall and that have higher temples.
If your face is oval
Almost any eyeglass shape works on this face type. Generally, however, the frames should be as wide as or slightly wider than, the broadest part of your face.
If your face is long
Oval glasses or ones with strong horizontal lines shorten the appearance of the face and soften its angles. Details on the arms can also help to draw the focus outwards.
If your face is narrow
Go with smaller frames as oversized versions can appear bulky. Rounded lenses flatter angular features plus embellished side pieces give the illusion of a width at your temples.
If your face is square
Curved shapes that are wider than they are tall will soften the angles of this face shape. Keep in mind, frames that are flat along the bottom can look boxy.
If your face is wide
Choose larger, wider frames (too small glasses can look cartoonish), and look for side pieces with spring hinges that will sit snugly on your head without squeezing it.
If your face is an inverted triangle
Balance your face shape by choosing frames with an emphasis on the top--aviators or half-rim versions work best.
If your face is heart-shaped
Oval, slightly rounded or butterfly shapes help soften heart-shaped faces.
Follow your nose
If you have a long nose, glasses with a low, prominent bridge break up the length. Ornamentation on the arms widens the face and can help divert attention. If you have a small nose, choose glasses with a high bridge in order to expose as much of the nose as possible.
Delicate metal frames are usually more flattering than heavier ones. A dark bridge can elongate a wide nose, but the bridge should be thin and simple so as not to call attention to itself. Rimless or metal frames with high-set arms and adjustable nose pads are the most flattering.
Match your brows
The most flattering glasses follow the curve of the eyebrows. With the exception of the oversize frames, be sure that your brows are always visible above the frames.
How to choose the right color
The colors that flatter you in clothing will most likely flatter you in glasses as well. Look for something that either complements your skin tone and hair color or is an attractive contrast (such as blond hair, pale skin and black glasses).
