TWICE’s Sana Addresses Backlash Over Controversial Underwear Outfit

TWICE’s Sana is facing backlash over her outfit at a recent event.

The controversy began on June 18, when TWICE attended the TEAZEN x TWICE Kombucha Lab pop-up in Seoul. Sana wore a floral dress paired with very short matching bottoms that caught fans’ attention.

Some netizens speculated Sana had accidentally tucked her dress into her underwear, while others questioned if the revealing look was intentional.

Fans quickly reacted online, sparking serious discussion about the outfit choice.

As the situation unfolded, Sana addressed the criticism on the Bubble messaging app. She explained that she had made sure the gap in the front of her dress was covered during the fitting. However, in the hectic moments before entering the waiting room, she didn’t check the mirror and the gap was left open.
