Harry Styles's Fashion Transformation, from Popped Collars to Statement Suits

Harry showed off his layering skills during an appearance with his One Direction bandmates by popping both the collar of his blazer and the polo he wore underneath. 

Before his wild, printed suits, Harry kept things simple with classic, tailored pieces like this prep-school blazer with white trim and an embroidered crest. 

Every once in a while, you feel like going back to basics, even if you're Harry Styles. The singer wore a classic white button-up shirt and black blazer to the New York premiere of One Direction's film This Is Us.

At the premiere of One Direction's concert film This is Us, Harry spiced things up by adding a monochromatic heart-printed shirt to his all-black look. 

Harry's long-term relationship with leopard print began with the T-shirt he wore to the Burberry SS14 fashion show. 

To accept his award for Style Icon of the Year, Harry wore a sheer button-up shirt, thin polka-dot scarf, and blazer to the 2013 British Fashion Awards. The vibe: prep school student with a Rolling Stones obsession.  

We're calling the forest green suede coat that Harry wore to the Burberry fall 2014 fashion show, the gateway into his preference for bold, loud, and printed ensembles. 

At the 2014 American Music Awards, Harry went for a full-on, all-black rock and roll look with a wide-brimmed hat, embroidered tunic, and blazer.

Practical and fashion-forward, Harry's black Calvin Klein sweatshirt and skinny jeans combo less basic by tying a paisley- and skull-printed scarf around his floppy hair.

Partially buttoned, oversize shirts in every print and color—like this pink polka-dot one Harry wore while performing with One Direction at Apple Music Festival—have become an onstage and offstage style staple for the singer.

When it's too warm out to wear a shearling coat, but too cool to go out in just a tee and skinny jeans, Harry throws on a fuzzy Saint Laurent vest.

Proving that leopard print can be appropriate for any occasion (including hanging out with Queen Elizabeth II), Harry wore an animal-print jacket to attend the Royal Variety Performance with Britain's royal family.

Harry's solution to never being too overdressed at the function: Take a cue from Mick Jagger and wear a skinny scarf instead of a black tie. 

A silk embroidered Saint Laurent jacket is foolproof way to make a T-shirt and jeans combo look more rock and roll. 

Harry wore a geometric tailored Gucci suit to a Miu Miu party during London Fashion Week.

The floral Gucci suit that Harry wore to 2015 American Music Awards may have launched a thousand memes, but we challenge you to find a sexier looking couch.

File these black and white pinstripe pants under the running list of examples that when you're Harry Styles, no trouser is too flared.

For his debut solo Saturday Night Live performance, Harry went for a classic vibe with a double-breasted, plaid Gucci suit. 

Mastering the one-shoulder coat drape solidified Harry's status as a street style star. The Gucci logo sweatshirt helped too (shop similar styles here).

For his Today show performance, Harry swapped his beloved printed suits for an Edward Sexton pink one of every millennial's dreams.
