Style it with your shape

For A Round Face

The key features of a circular face are soft curves, a rounded jaw-line and similar length and width.

Angular sunglasses will add definition to this face shape, deep colours will minimise fullness and gradient lenses will help to elongate the face.

Tortoiseshell and warm caramels are good colours. Thicker frames with wide temples also suit round faces, but this face shape should always stay clear of round sunglasses.

For A Heart-Shaped Face

Heart-shaped faces have a broad forehead and cheekbones with a tapered chin.

Look for thin, light metal or clear plastic sunglasses that have broader bottom halves – such as angular or aviator shapes – to balance the width of the chin.

Avoid dark colours, as they tend to cut up the line of the face.

For An Oval-Shaped Face

Though an oval face shape is well balanced overall, it's longer than it is wide which should be kept in mind.

Slightly square teardrop lenses look great on this type of face along with oversized lenses such as aviators.

Avoid angular styles such as rectangular sunglasses though, as they may narrow the face.

For A Square-Shaped Face

The defining features of a square shaped face are a strong jaw-line with an equally broad forehead.

The aim here is to soften the defined lines: this can be achieved by selecting circular styles and teardrop-shaped lenses.

Metal frames will make the face appear softer; black or single-colour frames are flattering too.

Avoid square or rectangular shapes as they draw attention to the angles and may give the appearance of a shorter head.
