It’s time to update your hater blockers and make sure they compliment  the shape of your face. The key is to experiment with different colors and shapes and pick out sunglasses that make you feel your very best, regardless of the rules. Here are some tips to help you along the way. –mckenzie harris

Choosing the Right Size

To get the perfect fit, imagine your face is being divided into thirds (your forehead being one third, the sunglasses being the next, and the mouth and chin being the rest). If your sunglasses take up significantly more or less space than the other thirds, switch to a different size.

Tip: More hair can carry more frame. So if you’ve got big hair, don’t be afraid of oversize glasses.

Kelly Rowland

Long Face

Yes: Oversize or wrap styles

No: Frames that are too narrow for your face

Your Profile – Longer than it is wide, usually with a larger forehead.

Frames should cover as much of the center of the face as possible in order to minimize length. Oversize shades work best. Details at the temples are also a great way to add visual width.

Amber Rose

Oval Face

Yes: Any shape works on you.

Your Profile – The most balanced shape with well-placed features.

The oval-shaped face can wear almost any frame style. The best way to choose? Take pictures of yourself in different glasses.

Rosario Dawson

Square Face

Yes: Round, oval, cat’s-eye

No: Sharp geometric shapes — they emphasize an angular profile

Your Profile – Strong jawline and equally broad forehead, with predominantly straight lines from top to bottom.

Pick frames that are slightly rounded at the edges to soften and balance features. Get frames that sit high enough on the face to downplay the sharpness of the jawline.

Kerry Washington

Heart-Shaped Face

Yes: Cat’s eye, round

No: Overly embellished glasses

Your Profile – Broad at the forehead and cheekbones and narrow at the chin.

To broaden the appearance of the chin and draw more proportion throughout the face, try thin, light metal or clear plastic frames that have broader bottom halves.

Gabrielle Union

Round Face

Yes: Wide, rectangular frames

No: Round frames or colored lenses, which exaggerate fullness

Your Profile: Soft curves around the jaw and a wider face.

To downplay the roundness, select frames with straight or angular lines. Deep colors, such as black or tortoiseshell, minimize fullness.
