The term ‘style icon’ conjures a familiar carousel of faces: Steve McQueen, David Beckham, James Dean, Ryan Gosling. And fair play, these men have earned their places in the menswear hall of fame.

But they’re not the only ones. For every Marlon Brando or Robert Redford, there’s an up-and-comer who deserves your respect, not to mention some study. Emboldened by youth (and the odd Hollywood stylist, admittedly), the young men below have found their look years earlier than the rest of us managed.

Some of them aren’t yet old enough to have their own credit card, but they have a clear sense of what looks good. They also know the rules – and when to break them. When they experiment, it usually works.

From streetwear to tailoring, on-screen glamour to off-duty casuals, prepare to get schooled by the next generation of style icons.

Fionn Whitehead

Dunkirk triggered a slew of military-inspired haircuts, outfits and episodes of PTSD. However, its breakout star Fionn Whitehead is just as stylish as his on-screen counterpart.

“Whitehead boasts a clean, classic appearance on the red carpet that’s offset by small details,” says Sarah Gilfillan, founder of personal styling consultancy Sartoria Lab. And it’s these touches that add depth to relatively innocuous looks: a subtle check, for example, or a silk lapel.

It’s a move easily emulated. “Introduce your own fitted polo or long-sleeved knit, buttoned up to the top. This channels a 1950s style best worn with a razor-sharp suit.”

A knitted polo also lets you flex some colour. Chime the shade with other pieces for a tonal look like Whitehead, or contrast navy tailoring with on-trend mustards or greens for a subtle nod to the forces.

Chance Perdomo

As the world’s first pansexual warlock, it’s unfathomable that British actor Chance Perdomo would have a wardrobe that’s anything short of magical. Star of The Sabrina the Teenage Witch reboot The Chilling Adventures of Sabrina, the young Londoner is quickly making a name for himself on both sides of the pond.
