J.Y. Park took the stage at Waterbomb Seoul 2026 on July 26, making an elegant entrance dressed in a classic tuxedo.

However, the formal look didn’t last long. As the performance progressed, he gradually removed his jacket, shirt, and trousers, eventually revealing a bold green mesh outfit underneath. The sheer ensemble, jokingly dubbed a “window screen” outfit by Korean netizens because of its net-like appearance, immediately became one of the festival’s most memorable fashion moments.

The dramatic costume change perfectly matched Waterbomb’s energetic atmosphere and set the stage for an electrifying performance.

After the costume reveal, J.Y. Park performed alongside fellow singer Rain (Bi) in a high-energy dance routine beneath Waterbomb’s signature water cannons. The pair’s synchronized choreography, charismatic stage presence, and playful chemistry quickly sent the crowd into a frenzy.

Many fans praised the performance for combining humor, confidence, and strong live entertainment, demonstrating why both artists remain celebrated performers decades into their careers.

Clips from the performance quickly spread across social media, where fans flooded comment sections with praise. Some of the most popular reactions included:

  • Only J.Y. Park could pull this off.
  • A true entertainer.
  • An artist through and through.
  • Waterbomb isn’t complete without J.Y. Park.

International fans also joined the conversation, affectionately referring to him by the longtime fan nickname “JYPapi,” while applauding his confidence and sense of humor.

Beyond the outfit itself, many viewers were amazed by J.Y. Park’s physique. Fans commented that it was hard to believe the performer is 54 years old, praising the toned physique he has maintained through years of disciplined exercise and nutrition. His appearance reignited discussions about the strict lifestyle he has often shared publicly, with many describing him as one of K-pop’s best examples of long-term self-discipline.
