1 / 7
Small heads prefer small frames that don't over-power. Cat eyes work well, as do these slim, modified Merona aviators.
2 / 7
Wide frames suit bigger heads, so people with larger noggins can play with oversize vintage glam. We like these Gradient sunglasses from Target.
3 / 7
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.
4 / 7
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.
5 / 7
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.
6 / 7
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.
7 / 7
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.
