Calvin Klein and Jung Kook launch biker-inspired capsule collection

Calvin Klein just gave its clean basics a biker slump: Jung Kook’s 20-style capsule pushes underwear, denim and tees into a low-rise, baggy silhouette with enough attitude to feel built for the street, not the boardroom.

The strongest pieces are the ones that twist the brand’s familiar uniform without breaking it. Trucker jackets, graphic tees, sweatshirts and a racer jacket make up the hard edge here, but the real pull is in the proportions: low-rise baggy jeans that loosen Calvin Klein’s usual fit language and make the whole capsule feel more current. This is the kind of styling shift streetwear people clock immediately. It is not about logos screaming louder. It is about the cut sitting differently on the body.

Jung Kook’s first hands-on fashion design collaboration with Calvin Klein also matters because it moves him out of the safe lane of campaign star and into actual co-creator territory. He became a Calvin Klein global ambassador in March 2023, then fronted the brand’s Spring 2026 denim campaign on February 24, 2026. This capsule is the next move, and Calvin Klein is smart enough to give it a separate identity with the co-branded mark CKJK EST. 2026. That branding tells you the company wants this to read like its own mini-universe, not just another celebrity face plastered over essentials.

The reference point is Jung Kook’s “rebellious and edgy style” and motorcycle influence, and that tracks with the clothes. Calvin Klein has always sold basics with sex appeal, but this collection leans harder into a biker-coded silhouette that feels closer to the baggy-denim, utility-jacket mood running through streetwear right now. It is less about reinventing the Calvin Klein wardrobe than pushing it sideways into a shape that feels more lived-in and a little more dangerous.

The rollout is built for demand. The collection goes live online on May 19, 2026, and in select stores on May 20. In Japan, online sales begin at 7:00 a.m. JST on May 20, with My Calvins members getting early access from 7:00 a.m. to 9:59 a.m. JST. Sales will run at seven stores nationwide, and some locations will use LINE ticketing or reservation systems for the first days, with purchase limits set on same-item, same-color purchases and underwear capped at seven pieces.

A global campaign and retail pop-ups in Los Angeles, Singapore, Sydney, Melbourne and other Asia-Pacific markets will keep the capsule moving beyond the feed. A Kuala Lumpur pop-up at Starhill Piazza will run from May 20 to 24, with each registered guest given 20 minutes inside. That is the clearest sign of what Calvin Klein is really selling here: not just Jung Kook’s name, but a version of the brand that knows its essentials need a sharper stance to stay desirable.
