BTS' Jungkook has partnered with Calvin Klein for the brand’s Spring 2026 campaign, set to be released on October 28. This marks his third team-up with the fashion label, continuing a streak of his previous work as a global ambassador for the brand.The new line sticks to CK's bold-meets-clean aesthetic. However, it adds the SEVEN singer's touch, underwear, and denim piece.

The clip includes scenes of neon lights and empty streets. “On the way. Watch this space," the post was captioned.
