Jung Kook × Calvin Klein 'CKJK' Collection Launches Retail — Sells Out in 30 Minutes in U.S., 1 Minute in China

The Jung Kook × Calvin Klein 'CKJK' collaborative fashion collection enters retail availability on May 20, 2026, following its online launch at 6 PM EST on May 19. The 20-piece capsule collection (priced $29–$699) sells out across the United States in under 30 minutes. In China, the leather jacket sells out in under one minute. The sellout extends to major markets in Europe, Southeast Asia, and Latin America within hours of the retail launch. The CKJK collection — Jung Kook's first major luxury fashion collaboration — features co-branded underwear, denim, outerwear, and accessories designed with Calvin Klein's minimalist aesthetic. The launch comes while Jung Kook is performing as part of the BTS ARIRANG World Tour, which arrives in Las Vegas for four Allegiant Stadium shows starting May 23. STARNEWS Korea confirms the worldwide sellout on May 21. Fan community frustration surfaces on social media over HYBE announcing a BTS 'SWIM' merchandise drop (via Weverse Shop, May 26) just one day before the CKJK launch, with many ARMY members calling the timing poor.
