Don’t underestimate the transformative power of a stylish pair of shades that actually fit your features.

Buying sunglasses can be a shady business. As brands proliferate, and styles multiply, we’re often dazzled by the ranges on offer, and forget to train our lens on what’s important – shape and fit. Pick a pair that complements your facial features, and you’ll instantly up your frame game.

Who’s got it: Mr Kanye West, Mr Tom Cruise Go for: frames that contrast well with your softer features; the goal is to create as much definition as possible. Frames that are slightly wider than your face, such as aviators, will make your cheeks appear slimmer. Angular frames (such as Wayfarers) elongate your temples and lengthen your face. Avoid: round frames that mimic your face shape. You would, quite literally, be going round in circles.

Who’s got it: Mr Ryan Gosling, Mr Jude Law Go for: almost anything, because – congratulations, respect due, etc – you’re blessed with the most coveted, compatible face shape of all. Avoid: arms that hang too low, because they further elongate your already adequately distended features.

Who’s got it: Mr George Clooney, Mr Russell Brand Go for: thick frames or oversize lenses to balance out your narrow proportions and soft features. Try vintage styles with clean, bold lines or aviators – the convex shape and teardrop silhouette of their lenses accentuate the vigorous line of the cheek and jaw bones. Avoid: more diminutive styles that make your features appear pinched and may provoke wearisome enquiries of the “why the oblong face?” variety.

Who’s got it: Mr David Beckham, Mr Jake Gyllenhaal Go for: rounded or slightly curved frames that will complement your strong facial structure. Avoid: anything too boxy or too sharp. So-wrong-it’s-right-angled is a challenging look to pull off.

Who’s got it: Mr Johnny Depp, Mr Justin Timberlake Go for: rounder frames, to help balance the wider forehead, or bottom-heavy frames, to help broaden the lower part of the face. Avoid: teardrop lenses or frames with too much detailing at the top. You’re looking to bolster the region south of the nostrils.

Who’s got it: Mr Kiefer Sutherland Go for: retro-inspired, rectangular styles that complement your defined chin and sharp cheekbones. You’ve got the canvas to experiment with strong colours and creative details. Avoid: extremes, particularly rounded, curved and angular. You’ve got the carats; you don’t need the stick.

Who’s got it: Mr Matt Damon Go for: top-heavy frames that pull the emphasis upwards and offset your broad jaw and chin; teardrop lenses can draw the eye up to the forehead. Anything with a heavy browline adds width to the upper portion of the face, which is where you need ballast. Avoid: anything that adds to bottom-heaviness. You don’t want to put the SOS in isosceles.
