The Harry Styles Lookbook

Let's be honest here: No one—not you, not us, not big-name designers, nor the influential brands they work for—would have believed that the wire-framed, floppy-haired guy from One Direction would wind up being one of the most stylish men alive today. But we're damn glad it happened. Because while rock 'n' roll music might be waning in popularity, rock 'n' roll style is more prevalent than ever and almost no one waves that sartorial flag higher than Harry Styles.

It turns out the Brit singer was the perfect billboard for Hedi Slimane's reimagined Saint Laurent wares, inspiring style-minded guys everywhere to yank on some skintight black jeans, suede Chelsea boots, and the best topcoat they could find. But Styles isn't a one-trick pony. Once he aced proto-rock-god style, the singer got in touch with his glam rock side, pulling off menswear that, on paper, shouldn't work (see: wallpaper florals and pussy-bow blouses by Gucci's Alessandro Michele and sequin-happy suiting from Givenchy) but that somehow looks, well, dope on him. And that's the hallmark of someone with true personal style: Whether you're deep in a printed tiki-shirt phase or drastically changing up your haircut, you're pulling it off with ease. Here's proof that Harry Styles is doing just that.
