JENNIE delivered another unforgettable fashion moment at Summer Sonic 2026 in Tokyo, taking the stage in a custom Calvin Klein Collection mini dress created from upcycled Calvin Klein denim waistbands.
The innovative design transformed one of the brand’s most recognizable details into a bold performance look. Individual denim waistbands were reconstructed and layered to form a sculptural mini dress that celebrated Calvin Klein’s heritage while offering a fresh perspective on denim and circular fashion.
Underneath the dress, JENNIE wore a white Calvin Klein Collection bra, creating a clean contrast against the various shades and textures of the reclaimed denim. An archival Calvin Klein leather belt completed the ensemble, adding another reference to the fashion house’s history.
A Creative New Approach to Calvin Klein Denim
Rather than using traditional panels of fabric, the custom dress highlighted the construction details that are often overlooked in a pair of jeans. Waistbands, belt loops, seams, labels and distressed edges became the central design elements.
The reconstructed denim created dimension and movement while giving the mini dress an intentionally raw, deconstructed finish. Each waistband contributed a different wash, texture or detail, making the garment feel like a wearable collage of Calvin Klein denim history.
The design also reflected the possibilities of upcycling. Existing materials were not simply reused—they were elevated into a one-of-a-kind stage piece created specifically for one of the world’s most influential performers.
JENNIE Brings Upcycled Fashion to the Festival Stage
JENNIE’s decision to wear the reconstructed design placed upcycled fashion in front of an enormous international audience. While sustainability is frequently discussed within the fashion industry, a major performance look can demonstrate its creative potential in a way that feels exciting and immediate.
The mini dress proved that upcycled clothing does not have to appear basic or unfinished. In the hands of Calvin Klein Collection, discarded or previously used denim components became the foundation of a striking custom garment.
Its fitted, abbreviated silhouette was ideal for the energy of JENNIE’s Summer Sonic performance. The layered waistbands created visual impact without restricting her movement, while the white bra and archival belt reinforced Calvin Klein’s signature combination of minimalism, sensuality and American sportswear.
A Celebration of Fashion History and Reinvention
The archival leather belt connected the experimental dress to Calvin Klein’s past. Paired with the upcycled denim, it created a conversation between preservation and reinvention—two ideas that are becoming increasingly important as fashion houses reconsider how their archives and existing materials can be used.
JENNIE’s second Summer Sonic outfit also complemented her earlier Kate Moss-inspired Calvin Klein look. While the first ensemble revisited a recognizable design from the brand’s Spring/Summer 1993 runway, the reconstructed mini dress explored how Calvin Klein’s denim heritage could be taken apart and rebuilt into something entirely new.
Together, the two custom looks represented different approaches to fashion history. One revived an archival silhouette; the other used familiar brand elements as raw material for a contemporary creation.
JENNIE Continues to Make the Stage Her Runway
JENNIE has developed a reputation for turning performance wardrobes into major fashion moments. Her clothing is never separate from the presentation—it becomes part of the atmosphere, movement and identity of the performance.
At Summer Sonic 2026, the custom denim-waistband dress brought together music, craftsmanship, sustainability and fashion history. It was playful, unexpected and immediately recognizable as Calvin Klein, even though it was unlike a conventional denim garment.
By transforming upcycled waistbands into a high-impact mini dress, JENNIE and Calvin Klein showed that the future of fashion may be found in reimagining what already exists. The result was more than a second stage outfit—it was a creative statement about the enduring possibilities of denim.
