Summer's just around the corner!

One of the easiest ways to change up your style (and protect your eyes) is with a new pair of sunglasses!

So which sunglasses suit you the best? toofab breaks down the most common face shapes -- round, square, oval and heart-shaped -- and recommends styles to flatter to your face.

Round faces

Description: You have fuller cheeks, a rounder chin, and few angles.

Celebrities with round faces: Kelly Clarkson, Elijah Wood, Kristen Dunst, Kanye West

Recommended style: Rectangular frames will add angles to your face, and make your face appear longer and thinner. Round frames are a no-no, they'll only emphasize the roundness of your face.

Simple and solid is the way to go. If you want something a little less angular, try a soft square frame. If you're feeling a little sportier, try this style.

Square faces

Description: You have a broad forehead, square jaw and square chin

Celebrities with square faces: Lea Michele, Tom Cruise, Olivia Wilde, Demi Moore

Recommended styles:

For men, the soft square (see above) work, but the rounder the better.

Oval bottoms are flattering, as are round ones.

For women, there are a couple of options.

Giant sunglasses are a celebrity favorite. Try these if you want to go glam but not so giant.

Oval faces

Description: Your proportions are balanced.

Celebrities with oval faces: Angelina Jolie, Channing Tatum, Zoe Saldana, Liv Tyler

Recommended style: You're lucky. Any style will work with your face.

Men can choose the classic aviator, but why not experiment with some trendier styles?

We like the modern hipster and sleek sport style.

Women can accessorize anyway they choose.

Feminine takes on men's styles and bold colors are totally in.

Heart-shaped faces

Description: You have a broad forehead, narrower jawline, and narrow chin.

Celerities with heart-shaped faces: Zac Efron, Hayden Panettiere, Leonardo DiCaprio, Halle Berry

Recommended style:

For men, a bottom heavy frame -- like the classic aviator -- help balance out the broadness of the forehead.

You can't go wrong with an aviator or this bestseller.

Women can get away with a cat-eye style, which complements your face shape.

We love this modern take on the classic cat-eye. There's a chic, slightly more rounded version too.
