Sana wore a floral outfit that consisted of a dress and very short matching bottoms.

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

On the Bubble messaging app, Sana responded to the criticism. She said that she had been mindful to cover the gap in the front of the dress, but she ended up not checking in the mirror to make sure the gap was covered before she entered the waiting room.

Even though the outfit became one of the most talked about parts of the event, Sana took the mishap in stride, brushing it off as a minor incident.
