JJ Lin has come a long way since he made his singing debut more than 17 years ago. Not only is the homegrown singer-songwriter now one of the biggest stars in Mandopop, but he is also a successful towkay and is raking in the big bucks. While his talent and success have remained consistent, his physique and style sure have changed over the years. As he turns the big 4-0 today (Mar 27), we look back at his evolution from boy-next-door to Hypebeast.

Fresh off his debut, JJ wooed the crowd with his flawless vocals as well as an oh-so-trendy outfit consisting of a summer scarf, a sleeveless black shirt, and river wash denim.

We completely forgot that JJ once sported spiky hair.

JJ’s “Cao Cao” era was perhaps his most stylistically experimental, as he tried everything from waistcoats with sleeveless shirts, to fedoras, to feathered locks.

JJ’s tartan shirt, silky suit, and Bieber hair might have blended in with the photo wall, but considering how each of those elements have aged, that’s probably a good thing.

At a Red Cross charity event championing single-parent families, JJ wisely threw on a black blazer over a khaki top and pants.

JJ celebrated the New Year, as well as the success of his album, She Says, in a festive sequinned scarf.

We’re not sure which is louder — JJ’s tight red pants, or that luxury sports car.

Again, we’re not sure what’s going on with those pants, but JJ sure can rock a skinny tie.

This phase of JJ Lin’s style choices is all but forgotten. Probably for the best.

Hot off the heels of his ninth studio album, Lost N Found, JJ appeared on stage wearing an embellished suit jacket with what appears to be a cape.

JJ attended the Spring Wave Music and Art Festival press conference in a dapper waistcoat with princely boots.

You know what they say about real men and pink. We’re not sure about the penguin-esque effect of those high-waisted pants and black waistcoat though.

Who wears vaguely Christmassy outfits in mid-August? Only JJ.

JJ showed off his bad boy side at the press conference of Hong Kong’s Spring Wave Music and Art Festival.

For the unveiling of his Madame Tussauds wax figure, both JJ and his likeness donned apparel from his own streetwear label SMG. No better way to promote your own line.

GO FOR THE GOLD: We love how JJ not-so-subtly coordinated his shoes and his sweater.

JJ looked more like a rock star than ever in his shiny statement overcoat at the Hito Music Awards in Taipei.

JJ, who usually sticks to trim silhouettes, tried a baggier aesthetic at the Louis Vuitton Menswear Fall/Winter 2018-2019 show during Paris Fashion Week.

While much has changed over the years, JJ's love for plaid remains consistent — as evidenced by this stage costume from his JJ Lin's Sanctuary World Tour show.

JJ flaunted elevated street style in an Off-White jersey, distressed jeans and Undercover x Nike kicks.

When attending a K-pop music awards ceremony, you have to look the part, and JJ is giving us the perfect blend of flamboyant and sharp.

JJ was all nerdy chic in his geeky glasses, tousled hair, and preppy yet quirky getup. Love the Dior bee pants!

We’re pretty sure JJ turned heads when he showed up at Paris Fashion Week in this dapper Louis Vuitton white suit and harness.

Nothing to say here, just plenty to see. In case you're wondering why JJ is half-naked, the singer promised to take his shirt off if he hit the milestone of 50 million followers on Weibo.

JJ dressed the part when he attended the Wimbledon in this dashing school uniform-inspired suit by Polo Ralph Lauren.

Posey pose aside, JJ looked pretty dapper in this cream houndstooth suit by Ralph Lauren.

JJ looked like he walked straight out of a sci-fi movie in his futuristic outfit complete with visor and metallic hair.

This kimono jacket over a striped shirt look gets a kimoYES for us!

JJ looked as dreamy as the clouds on his Louis Vuitton suit while performing at the Golden Melody Awards.

The OCD in us is itching to untangle those chains.

JJ has always been experimental with his outfits, and it looks like he was all about exuding an air of dark mystery and understated luxe in this street style-worthy getup.

We never thought we'd see JJ in a leopard preenz but he looks kinda cool in it.

Creepy face paintings aside, we like how JJ's CNY outfit features a bottle of hand sanitiser — a nice reminder to everyone to stay safe and clean when visiting.

Dressed in a black tailcoat for the recent A Night Of Disney+ showcase, but we think JJ looked much like Tuxedo Mask from Sailormoon — in a good way. All that’s missing are a top hat and eye mask to complete the look.

He's pretty well-dressed for someone who's in quarantine.
