Harry Styles' total fashion transformation, from teenage heartthrob to bonafide rockstar

Harry Styles reigns king of printed statement suits, often accented by flowing brown locks and a cheeky smirk—and that's why we love him.

Styles got his big break as a 16-year-old heartthrob on the UK's "X Factor" back in 2010. As a member One Direction, he often donned blazers in solid colors—playing with different textures such as tweed and velvet—layered over t-shirts and paired with slim-fit pants and sneakers.

In 2014, as the band launched their fourth album appropriately titled "FOUR," Styles began to experiment with prints in button down shirts, pants and scarves. He also famously let his hair grow in volume and then in length, and fans continued to swoon.

2017 was a big year for Styles, professionally and fashionably. He made his acting debut in "Dunkirk" and released his first solo album. Consequently, he emerged with a new set of brightly colored and campy printed Gucci suits, along with a shorter, more quaffed haircut.

Styles had been wearing Gucci for a while, but that year the fashion house announced that while on tour, the singer would wear a selection of one-of-a-kind pieces designed by Creative Director Alessandro Michele. One of our favorite looks includes a custom pink and khaki floral-printed velvet jacket paired with matching bell bottoms.

Then, in 2018, it was (finally) announced that Styles would become an official face for Gucci men's tailoring.

Most recently, in March he made his first official public appearance of 2019 at the Rock and Roll Hall of Fame Induction Ceremony in New York City sporting a bright blue velvet suit from Gucci's pre-fall 2019 collection.

Styles is set to attend his first Met Gala in NYC on May 6th as a cohost with Lady Gaga and Serena Williams, and with a theme like "camp," he's bound to nail his red carpet look.
