Round faces feature noticeable curves and fewer defined angles. Opt for glasses with sharp angular lines to elongate and refine your face. Rectangle, square, wrap, and shield-shaped glasses complement round faces well.

Square faces have similar lengths and widths, with broad foreheads and strong jawlines. Round or oval-shaped glasses help soften the face's sharpness. Consider aviators, butterflies, or round frames. Center or top-set temples are suitable for square faces.

Oval faces are versatile, and most frame styles suit them. From designer to sporty frames, oval faces can rock any look. Avoid oversized frames that hide your symmetrical features.

Rectangular or oblong faces are long and narrow with few angles. Oversized sunglasses, large wayfarer or rectangular lenses with thick frames, or sunglasses featuring tall or deep lenses work well to add width and edge. Styles like wrap, shield, square, wayfarer, and rectangle are great options

Diamond-shaped faces have narrow jawlines and foreheads, with wide cheekbones. Opt for oval and rimless frames to complement your cheekbones. Choose frames with gentle curves that don't extend beyond your cheekbones' width.

Heart-shaped faces are widest at the temples and narrowest at the chin. Look for sunglasses with wide lower edges and no straight lines on top to balance your features. Cat-eye styles, rounded edges, shield, butterfly, rimless, or aviator frames are ideal for heart-shaped faces.
