Jung Kook makes his design debut alongside Calvin Klein with ‘CKJK’, a collection inspired by biker culture and his own personal aesthetic.
The relationship between Jung Kook and Calvin Klein has officially entered a new chapter. After fronting some of the brand’s most viral and talked-about campaigns over the past few years, the BTS member is now stepping further into the fashion industry with the launch of his first collaborative collection with the American label. Titled ‘CKJK’, the capsule works as a direct extension of his visual identity: sensual, dark, rebellious and deeply rooted in biker-inspired aesthetics.
Rather than simply reworking classic Calvin Klein staples, the collection builds a far more defined visual universe. Premium leather jackets, washed brown denim, graphic T-shirts, crop tops and reimagined versions of the brand’s iconic underwear all form part of a capsule that merges Calvin Klein’s minimalist American DNA with the South Korean artist’s personal energy and style language.






One of the collection’s most striking elements is Jung Kook’s level of creative involvement. Several pieces incorporate details inspired directly by his tattoos, integrating them into T-shirts and bralettes as central design motifs. The newly introduced “CKJK” logo further reinforces the idea that this is not merely a promotional collaboration, but a project built around his own image and aesthetic sensibility.
The launch also reflects Jung Kook’s enormous cultural influence within contemporary global fashion. Every previous campaign starring the singer generated massive online conversation, with pieces repeatedly selling out within hours. Now, through ‘CKJK’, he transforms that commercial power into something far more author-driven and creatively personal.
Another aspect drawing significant attention is the scale of the collection itself. Unlike limited capsules focused purely on merchandise or a handful of statement pieces, ‘CKJK’ spans menswear, womenswear and intimate apparel. Pricing also reflects that diversity, ranging from more accessible pieces at $29 USD to premium leather jackets retailing for up to $699 USD.
However, some of the collection’s most exclusive items will only be available at selected flagship stores including Harajuku, Soho and Champs-Élysées, reinforcing the collectible and limited-edition nature of several designs.
