Tsuki of Billlie in low-slung jeans exposing bikini bottom sparks debate at Waterbomb Festival
Tsuki of Billlie sparked debate after performing in low-slung jeans that exposed the bikini bottom underneath at the 2026 Waterbomb Festival in Seoul.
Billlie performed at the festival with high-energy sets. Tsuki stood out in a teal top and ripped jeans, with matching eye makeup. She was also splashed from head to toe during the performance.
The styling drew online criticism after fans noticed her jeans were worn low, revealing the bikini bottom beneath. In some videos, Tsuki appears to drag the bikini bottom up during the set, which led many to think she was uncomfortable with the exposure. Others questioned whether the stylist failed to account for jeans getting heavier when wet and sagging lower.
Some posts criticized the styling:

I wish they’d pull up the girl’s pants.

코디가 다음부턴 좀만 더 생각해줬으면 좋겠네..
청바지라 물에 젖어서 무거워지는건 당연한거잖아.. https://t.co/eOA5DgHY2Z pic.twitter.com/UpBxcT5JrR— 꿍.. (@rrmeluu) July 25, 2026
I really wish the stylist would put a bit more thought into it next time…It’s obvious that jeans get heavy when they soak up water…

Waterbomb has always been kind of an event where showing skin is the whole point, so people really need to stop constantly going after the stylists…
