It’s hip to be square – from Mr Brad Pitt to Mr Henry Cavill, a strong, broad jawline is something of a Hollywood ideal for a man. But it can make buying sunglasses tricky. Anything too edgy or sharp will look blocky, so think outside the box. Rounded or curved frames will add an extra dimension to your chiselled features.

Rather than going round and round, let’s square the circle. By which we mean that if your profile is curved like Messrs Leonardo DiCaprio or Kanye West, you should avoid round sunglasses that mimic it. Angular frames will help lengthen your mug, while a pair that’s wider than it will make you appear slimmer. Sunnies that contrast with your face shape will add definition.

Let’s get straight to the point: defined cheekbones give you a lot to play with. If you’re cut like Mr Timothée Chalamet, retro and rectangular frames, say your classic Ray-Ban Wayfarers, are a good place to start. From there, experiment with colours and details, but don’t go too far – extreme curves or angles can put your face out of whack. Otherwise, shine on, you crazy diamond.

Long story short, a rectangular fizzog calls for strong frames to balance out your narrower proportions. Think thick rims with bold lines. Or aviators will work, as demonstrated by Mr Tom Cruise in Top Gun; the teardrop shape should accentuate your robust features.

With that face, you’re probably used to the compliments. Well, here’s another – when it comes to sunglasses, yours is also the most versatile shape. From oversized bug eyes to tiny Matrix specs, if you’ve got a profile like Mr Ryan Gosling, there’s nowhere you can’t go. One word of advice: avoid arms that sit too low or they’ll give you a hang-dog look.
