Like a modern-day Mick Jagger, One Direction's Harry Styles has that weird rockstar sex appeal that can be attributed, in equal parts, to his unwavering confidence and the fact that he looks good in tight pants. Not bad for a pop star who started out rocking cowl-neck sweaters and ill-fitting khakis on national television.

And while it's true that Harry isn't the fashion chameleon former bandmate Zayn Malik was, after a few public missteps he seems to have found his stylistic niche. Summed up best by Taylor Swift's Harry-inspired (and criminally under-promoted) 1989 track "Style," Harry's mostly about that "long hair, slicked back, white t-shirt," at least onstage.

But his everyday style is slightly more varied, and after years of growing out that artisanal bird's nest head of hair coupled with a sudden penchant for various hair accessories (including but not limited to: scarves, wide-brimmed witch hats and t-shirt scraps) he's blossomed into something of an unlikely fashionista. With his increasingly low-cut button-down blouses, a propensity for wearing things with a bold pattern, colorful heeled booties and flowing locks, Harry’s casual-cool style has become something to emulate — and we’ve got the photos to prove it.
