I’m a glasses expert – which sunglasses will suit your face shape and why you shouldn’t dismiss the bold cat’s eye look

Sexy, stylish sunglasses can make or break a summer outfit.

But when you’re shopping online it’s hard to know which shape will suit you – and you can’t try them on.

Here, Fabulous Fashion Editor Clemmie Fieldsend asks Specsavers’ frame stylist Bianca Swan which sunnies will present your face in the most positive light . . . 

Diamond

A DIAMOND-shaped face has a narrow chin and forehead, with wide, angular cheekbones.

Bianca says: “For those with this shape face, a rounded frame style will complement your features – but that doesn’t mean you can’t be adventurous.

This pair of cream shades are £15 at Marks & Spencer

“Try a round or oval metal frame, or make a statement with cat-eye frames to help accentuate your cheekbones.”

Square

IF your hairline mirrors your jawline in a horizontal line, you have a square face.

Bianca says: “Your defined jaw means you have a great face structure for angular frames.

This pair of oval tortoise-shell shades are £26 at Oliver Bonas

“To balance your features, we’d recommend narrow, oval frame styles – or you can opt for a bolder look with cat-eye or geometric shapes.”

Round

FULL cheekbones, a rounded chin and a wide hairline mean you have a round face shape.

Bianca says: “We recommend you go for styles that contrast and lengthen the look of your soft, curved features.

Oval

IF your face is longer than it is wide, with a jaw narrower than your cheek bones, then you’re an oval.

Bianca says: “Your face shape means you have a combination of soft and angular lines.

The oversized are just £3.50 at Primark

“Luckily for you, almost all frame shapes will suit you, so you can be as adventurous as you like.

“Make a statement with a geometric or oversized style, or opt for something more subtle like a teacup shape.”

Heart

HEART-shaped faces have a chin and jawline narrower than the forehead.

Bianca says: “Heart shapes feature both soft and straight lines, so the world’s your oyster when it comes to frames.

River Island has these classic Aviators for £14

“We recommend a Clubmaster style – that’s a pair with framing across the top of the lens, but not the bottom – or a cat-eye frame to complement your face shape. You’d look great in aviators, too.”

Pear

THIS face shape – sometimes known as an upside down heart shape – is when your jawline is longer or larger than your forehead.

Bianca says: “Having a pear-shaped face will mean your jaw is its widest, most prominent feature – so balancing this with more angular, stand-out styles will compliment you perfectly.
