The shade-y business isn't for everyone (forgive the pun). And most people certainly can't pull off shades. But that's only because they don't know what works for them and what doesn't. A major factor that you need to account for is your face shape. 

If you understand the dynamics of a pair of sunglasses and the shape of one's face, you can pull off shades like you've always wanted to.

Here's a quick guide for you to help you get the right pick:

With a round face, ideally stay away from anything that makes it look even rounder. Instead, choose glasses with angular frames like a square or a rectangle. These give an edge that balances out the roundness of your face. These frames will work on your face like a charm.

For a defined jawline with symmetrical proportions, your face would ideally fit in the square face shape category. You obviously don't want to look like a square-faced robot. Here, round glasses, break the line and will suit your face best.

Both face types have sharp, prominent cheekbones, that need complementing with other prominent structures. Aviators look the best with these face types. Try reflectors for a groovy effect.

If you have an oval face, you're one of the lucky ones. This blessed face shape works well almost any kind of shades. Take a cue from Ranveer Singh and go wild with the quirky ones.
