HOW TO FIT THE FRAME SHAPE TO YOUR FACE ?
Once you know your face shape, you’ll be able to figure out which frame shape gives your face a natural balance. When choosing frames, the best rule is to choose frames that are the opposite of your facial features. For example, a square or angular face looks great in a round frame, while round faces and softer features benefit from the contrast of a square frame. Contrast is also key to assessing the upper and lower parts of the face. If the top half of your face is wider than the bottom half, then your face should also be the opposite shape, and vice versa. If your features have warm tones, you should lean toward warm shades of red, yellow, orange, brown, chartreuse, and ivory frames. If you have cool skin tones, you should know the blue dominated reds, blues, grays, pinks, purples, teal and magenta. If you have neutral skin, you can pull off almost any color!(same to male and female)
round face

If you want to visually lengthen your face choose glasses with dark frames. They narrow the face and bring its contours closer to an oval shape. To balance your facial proportions, it’s best to choose a frame where the width is greater than the height.

oval face
Some people think that the oval face is the most balanced of them all, so in this case, the main goal is to not disturb your face’s harmonious proportions. Therefore, you should avoid glasses that look too massive. The frame should be as wide as your face, or a little wider. Make sure that the frame’s upper part is in line with your eyebrows.

squar face

Sharp-angled rectangular or square frames can “overload” your face’s outlines. Rounded frames will help to visually balance and soften overall facial proportions.

rectangle face
It’s best to aim to make your face appear visually broader. Go for large, massive-looking glasses. Also, make sure they have transparent lenses and slender frames that match the tone of your skin.

heart face

Your goal is to balance out the upper part of your face by making the lower part appear bulkier. Massive-looking glasses won’t help: they’ll just add more bulk to the upper part. We advise you to choose glasses where the width equals the width of your face. Opt for a teardrop-shaped design. “Aviators” would be ideal.

triangular face
Your main aim should be to visually broaden the upper half of your face while making the lower half less conspicuous. Choose sunglasses with a large frame and a broad upper part. The lower part shouldn’t have square or sharp outlines.
