Online discussions recently emerged around BTS member Jungkook’s newly launched CKJK collection with Calvin Klein, particularly over the sizing of its bralette designs. The limited-edition collaboration officially released on May 20, 2026, making the singer’s first official co-designed collection with the brand since becoming its global ambassador in 2023.
In addition to appearing in the campaign visuals, Jungkook reportedly contributed to the creative process behind the collection. Soon after the launch, however, social media users began debating whether the innerwears were inclusive enough for different body types.
Several fans expressed concerns that the designs might not provide enough support or sizing options for people with larger bust sizes. One user wrote,
“My 46I are not going to fit…not even close.”
Others shared similar reactions and humorous comments about the fit of the pieces.
Some users also noted that Calvin Klein’s innerwear products had often been perceived as running small. A few fans shared their personal experiences with the brand, saying they usually purchased larger sizes even when they wear smaller sizes in other clothing labels.
At the same time, other fans responded positively to the collection, saying they were happy to see styles that appeared better suited for people with smaller body types. Several users shared that they felt represented by the sizing and fit featured in the campaign.
BTS’ Jungkook’s CKJK collection sells out in 30 minutes amid global website crashes and sizing debate
The launch of BTS member Jungkook’s first collaborative collection with Calvin Klein drew major global attention following its release. Despite ongoing online debates surrounding the collection’s sizing, the limited-edition CKJK capsule reportedly sold out rapidly on the brand’s US website, with all 36 items becoming unavailable within 30 minutes. The brand’s website reportedly experienced heavy traffic issues and temporary crashes across multiple regions shortly after the collection launched.
The CKJK collection creats a new stage in Jungkook’s partnership with Calvin Klein after several years of the idol appearing in campaigns and shows as the company’s global ambassador. Unlike previous endorsements, the capsule reportedly involved the singer more directly in the creative development process.
Inspired by Jungkook’s interest in motorcycles and biker culture, the collection featured both menswear and womenswear pieces built around themes of freedom and individuality. The accompanying campaign adopted a cinematic biker-inspired concept while combining Calvin Klein’s signature essentials with elements connected to the singer’s personal style.
The lineup included denim-focused staples such as ’90s trucker jackets, straight-fit jeans, low-rise baggy silhouettes, graphic T-shirts, sweatshirts, racer jackets and underwear pieces. Several items also incorporated distressed denim finishes, racing stripe details, custom washes, hidden embroidery, interior woven labels and exclusive CKJK branding throughout the collection.
According to official product listings, prices for the capsule ranged from $29 to $699. Reports also stated that Jungkook participated throughout the development process, including discussions related to the overall concept, denim washes, and fit adjustments for selected pieces such as the trucker jacket.
In his career front, Jungkook is currently touring with BTS for their ARIRANG World Tour. The group recently wrapped up a three-night concert series at Stanford Stadium during the North American leg of the tour.
Speaking to WWD, Calvin Klein global brand president David Savman described the collaboration as a blend of Jungkook’s influence and the brand’s established design identity. To support the launch, Calvin Klein organized immersive retail pop-up events across several international cities, including Singapore, Sydney, Melbourne, Shanghai, Shenzhen, Chongqing, and Los Angeles.
BTS is next set to perform at Allegiant Stadium in Los Angeles on May 23, 24, and 27. Reports also suggest that the ARIRANG World Tour will later expand to additional regions worldwide, with more concerts expected across North America, South America, Asia, Australia, Europe, and Canada.
