Summers still have a long way to go but choosing sunglasses requires more understanding of algebra than one might suspect. Knowing your angles and lines and what shapes will flatter those angles and lines is very important for us. So we’ve broken it down for your ease – read  below to know which glasses look best for your face shape!

Small Head

Small heads prefer small frames that don’t over-power. Cat eyes work well, as do these slim, modified Merona aviators.

Big Head

Wide frames suit bigger heads, so people with larger noggins can play with oversize vintage glam. We like these Gradient sunglasses from Target.

Heart-Shaped Face

Heart-shaped faces – wide forehead and cheekbones with a narrow chin – should aim for cat’s eyes or rounder sunglasses while avoiding too much embellishment. We like these bold red Mossimo glasses.

Oblong Face

Oblong faces –  longer with narrow chins and cheeks – should steer away from narrow frames. But oversize or wrap styles work well, like these Nine West sunglasses with a cunning ’70s reporter vibe.

Oval Face

Oval shaped faces are lucky – any sunglasses work on you. Your balanced forehead, cheekbones, and jaw can carry off any style – like these Audrey Hepburn-esque vintage sunglasses.

Square Face

Square faces with a broad forehead and square jawline look well with round and oval frames, or these aviator sunglasses from Marc Jacobs. Avoid sharp geometric shapes. They emphasize an angular profile.

Round Face

The full cheekbones, narrow forehead and jaw of a round face are best flattered by wide, rectangular frames. Round frames or colored lenses exaggerate fullness. Try these squared off Athleta sunglasses instead.
