When a shop assistant in your favourite shop turns around and says “I don't think your face really suits those glasses,” it can be a crushing emotional affair. But with this little article, allow us to gradually put your mind at ease.

Because the truth of it is that not all sunglasses fit every kind of face. It's nothing to do with you not being pretty, handsome or a good-looking individual, either. In fact, the very notion that your face doesn't suit all glasses could be seen as a good thing. With a unique, attractive face, it's all about getting it right from the start. That way you'll never lose confidence and next time you wander into a shop to buy sunglasses, you won't have to put-up with feeling less than 100%.

❤ So you have an oval face

If you have an oval face, congratulations. Some of the prettiest and hunkiest celebrities in the world own this face shape, so it's not a difficult one to buy sunglasses for. So if you're wondering what constitutes an oval face, think about this. Your face has a balanced shape to it that works on a number of levels, and this is the one that many people wish they had. Appearing slightly longer than it does wide, the jaw will be a little narrower than the forehead.

And now moving onto what you need to find. Well, that's easy enough. You're almost certainly best off with sunglasses that are wider than the very widest part of your face. Going for this option maintains the crucial natural balance we all strive for, but if you'd prefer something else then it's also good to go with the “Walnut”.

What are walnut-shaped frames? Easy. They're frames that aren't particularly deep or very narrow. Yet in truth, as we said, you're a lucky one, as you can get away with wearing many different sunglasses and all will look just as good.

❤ Rectangular face shapes

Looking at yourself in the mirror and wondering what kind of face you have? Well, if you have a squarer chin and a longer face, don't worry. You have a rectangular face shape and all is good. To compliment your slightly longer but equally fabulous nose, you're best off with sexy square frames. If you're wondering why this is the case, then wonder no more. It's all about keeping the balance, and these sunglasses do that trick just right.

Next up, remember the golden rule. A frame with a lower-than-average bridge will do well, as it’ll work wonders with the appearance of a slightly longer nose. The great news is that there are tons of contemporary styles to suit all you lucky-lucky people. With this face type, it's all about keeping the length and width in balance, so that you can have the confidence that you deserve.

❤ So you have a triangular face

People have always said you have a broad forehead and a narrow chin, and you've never known what any of it meant. Well, today, there's no reason to fear, as it transpires that you have, yes, a triangular face. If you've been reading about oval faces and wishing you had one, then have no fear, as this face type is ideal for a wide range of sunglasses.

Look out for frames that keep the width of your upper face in-check. If you can find frames which are wider at the bottom then you'll be onto something good fast, as these place all the attention lower down the face.

Wondering what styles are out there to suit you? Have no fear. There are plenty of light-coloured sunglasses and rimless frame options that will make you smile. Rounded frames can be a fantastic option for you, as can small square frames, which add a level of balance to your cheeks and nose that other sunglasses might struggle with achieving.

❤ You over there, with the square face shape

You've a strong jaw and a face which is all about balance. With the width of your face matching the length quite precisely, you need to be exact with the sunglasses you choose. Well, have no fear, as we have all kinds of advice for you.

For example, one thing to remember is that softening angles is a good thing. Look out for narrow frames which have a bit of width to them, such as round or oval ones. Conversely, square-framed ideas should go out of the window. These won't suit at all and should be avoided at all times.
