If your face gradually narrows from the forehead down to the chin, with high cheekbones, you have a heart-shaped face. With the right frames, you can minimize the width at the top of the face while adding it to your narrow chin. "This is a very difficult shape to fit because almost any pair of glasses will add emphasis just where you won’t need it," says Kristie Whitford, who manages the fashion campaign for The Vision Council. She suggests frames that are wider at the bottom, such as aviator, butterfly or low-triangle styles with a rimless frame.
Your face is full of curvilinear lines -- the width and length are in the same proportions with few or no angles. Beauties such as Drew Barrymore and Kate Winslet have round faces, and both look great in eyewear. Choose frames that create angles and narrow the face, avoiding excessively rounded or squared styles, which will exaggerate the round shape. High temples will elongate the profile, and a clear bridge (nose piece) widens the eyes. Frames that are wider than they are deep, with subtle angles, will look best.
You lucky girl. The oval face is considered the ideal shape because of its balanced proportions, so most frames will look good on you. You have an oval shape if your chin is slightly narrower than your forehead, and your cheekbones are high. "With this shape, frames should keep the oval's natural balance," Whitford says. In other words, as long as the frames are in proportion to the size of your face, they'll look good on you.
A square face is characterized by a strong jaw line, a broad forehead, and a wide chin and cheekbones, with a normal width-length proportion. Think Isabella Rosellini and Sandra Bullock. When selecting frames, you'll want to choose ones that make your face look longer. Look for a frame that has some curve or uplift to draw attention away from the jaw line. Gently curved, top-heavy, narrow styles are your best bet.
The oblong face is much longer than it is wide (example: Sarah Jessica Parker) and has a long straight cheek line. "Because of the extreme length, the oblong face needs a frame that is deeper than its width, creating an illusion that makes the face appear shorter," Whitford advises. Try round, deep, or low-triangle shapes, or frames with strong horizontal lines. Decorative temples can add width to the face, so don't be afraid to get funky.
If you have a narrow forehead that widens at the cheek and chin areas, you have a triangle-shaped face. You'll want frames that add width to the forehead while narrowing the jaw, chin, and cheeks. "Try square, flat-top aviators, semi-rimless (no rim on the bottom half), or any eyewear with emphasis on the top half of the frame," Whitford says. Also, ones that are heavily accented with color on top, as well as cat-eye shapes will make any triangle-faced gal look fierce.
Just like the stones we covet, diamond-shaped faces are the most rare. They are narrow at the eye and jaw line, with a small forehead and chin, and high, dramatic cheekbones. "To highlight the eyes and bring out the cheekbones, try frames that have detailing or distinctive brow lines, or try rimless frames or oval and cat-eye shapes," Whitford suggests.
