Harry Styles
Musician, 27
In a word: delightful. That’s how we’d describe Harry Styles’s, er, style. Not only because his flared trousers, fantastical knitwear, and all-around panache make music and fashion fans around the world smile at the sight of him—though that’s true, too—but also because he looks like he’s having so much fun with his clothes (and nails, and everything else). Achieve even half of that enjoyment level yourself and you’re on the right track.
