A Well-Chosen Pair of Frames Can Elevate Your Whole Look...

So you know that you need glasses or sunglasses. What you don't know is what kind of frames will suit your face - and your style. Here's a quick guide to finding the best pair for you.

(Maybe you don't need glasses at all - and that's OK, too.)

The Key: Finding Your Face Shape

On-trend oversized sunglasses make your friend look chic - but when you try them on you look like an insect? Maybe they're the wrong pair for your face shape.

Here's a quick primer - complete with celebrity lookalikes and advice - to help you become your most stylish self.

Round Face

Think Gerard Butler, Charlize Theron, Selina Gomez, Leonardo DiCaprio.

The best shapes for you are rectangular and square. Choosing straight, angular lines will make the face appear longer and thinner.

Diamond-Shaped Face

Think Beyonce, Ashley Greene, Elijah Wood.

With wide cheekbones and narrow chin and forehead, the best glasses shapes for you are oval, square, and rimless.

Pro Tip: Make sure the frame is no wider than the top of the cheekbones to look your very best.

Oblong Face

Think Sarah Jessica Parker, Liv Tyler, Adam Levine.

With a longer, more-oblong face, the best glasses shapes are round and square. These shapes will make your face appear slightly shorter - especially if you go with styles narrower than the broadest part of the face.

Pro Tip: You're lucky enough to be able to pull off a decorative temple detail on your sunglasses - try it out!

Heart-Shaped Face

Think Johnny Depp, Halle Berry, Reese Witherspoon, Taylor Swift

You will look fabulous in semi-rimless, rimless, cat-eyes, and most styles with a straight top.

These shapes will help balance your lovely jawline. Make sure the frames don't sit too low on your face.

Pro Tip: Steering clear of extra large frames, heavy nose bridges, and square shapes will keep you looking at your very best.

Oval Face

Think Jessica Alba, Emma Stone, Ryan Gosling

Lucky you; with a well-balanced, oval face, most shapes will look great.

Try the on-trend oversized sunglasses, sporty wraps, rimless shields, or a classic rectangular shape - just about anything goes (well, almost).

Pro Tip: Make sure that the frame is in proportion to the size of the face for your optimal look.

Square Face

Think Henry Cavill, Olivia Wilde, Cameron Diaz.

The best shapes for you are oval, round, and cat-eyes. These shapes will reduce the angles and soften a square jaw. Make sure the top of the frames sit high enough on the face to draw attention upwards.

Pro Tip: Try sunglasses with a thinner frame to soften the look.

So There You Have It...

Once you've found your face shape, you'll only ever wear the best frames for your face. And get the best haircuts for that matter.
