Denim has never looked so good. Modeling Calvin Klein’s new Spring 2026 denim, BTS K-pop star and global brand ambassador Jung Kook has stepped out in his Calvins again for the brand’s latest campaign.

Directed and shot by Mert Alas, the campaign visuals get hot, hot, hot, highlighting the singer’s arsenal of attributes—his swagger, seduction, and sharp footwork. In the accompanying campaign video, the boyband heartthrob is pictured browsing a record store, cutting loose to the music, before actress and New York City legend Rosie Perez shuts him down.

There’s never a still moment for Kook. Even in denim, the K-pop icon never fails to deliver a performance—proof that Calvins aren’t just everyday essentials, but best-day staples.

“I love Calvin Klein jeans because they’re designed to be lived in,” says Jung Kook. “The looks I wore for this campaign nod to ‘90s style while feeling completely modern. It was exciting to bring together my love of music, dance, and fashion against the energy of the city.”

Emulating his own suave style, Kook wears Calvin Klein’s 90s Straight denim, a modernized take on the vintage straight-leg cut, along with relaxed-silhouette versions of the Baggy jean. Complementing the campaign’s hero denim, casual logo tees are slipped on (and off) alongwith new elevated denim washes of the iconic Trucker jacket.
