Best frame shapes for square faces shape:

Round frame glasses: Round glasses with rounded edges can soften a square face with sharp corners, and if paired with lenses that are slightly wider than the cheekbones, your face will be more symmetrical.

Oval-frame glasses: Oval-shaped glasses can soften the sharp angles of the face, balance the angular lines of the face, and increase the balance of the facial structure.

Aviator Frame Glasses: Aviator glasses are shaped like a teardrop with a curved bottom edge for a curved shape that adds a touch of softness to square faces.

Thin-frame glasses: Compared with thick-line frames, thin-frame glasses can dilute the seriousness of a square face.

Wider Frame Glasses: Frames that are wider than your face are best for square faces.

Rimless glasses: Rimless glasses can tone down the edges and cheekbones, allowing the best features to shine through.

Semi-rimless glasses: Half-rim glasses can draw attention away from the facial features to the glasses, creating a softer look.

Cat-eye glasses: Cat-eye glasses can help create a harmonious look by balancing the angular features of a square face.
Frames to avoid:
Square glasses: Angular, boxy square frames will sharpen angular features and make a square face look bulky.
Frame Width:
Choose frames that are wider than the widest part of your face. This can draw attention away from a thick jawline, creating the illusion of a thinner face. Avoid frames that are too narrow, as they may emphasize the squareness of your face.
Frame style:
Experiment with different frame styles to find the one that suits you best. Avoid frames with sharp, square corners or straight lines, as they will accentuate the angular features of your face. Instead, choose frames with gentle curves and soft lines.
Frame colors and patterns:
Consider choosing frame colors and patterns that add interest and draw attention to the upper half of the face. This can help balance proportions and draw attention away from the jawline. Bold or contrasting colors can be a good choice, but be aware of your personal style and skin tone.
Soften the edges: Since square face shapes are inherently angular, it is often recommended to choose frames that help soften those edges. Look for glasses with rounded or curved edges, as they can create a more balanced look.
Glasses that soften angles and sit high on the bridge of the nose are best for square faces. Oval or round glasses can balance the angles of a square face and make it appear thinner.
