On February 23, fans were worried for STAYC's Sieun as she was seen almost falling due to shoes that were too big for her. 

Compared to the other members, who were wearing relatively comfortable and form-fitting shoes, Sieun was seen wearing high heels that were clearly too big for her. What worried fans more was that there was a video showing Sieun almost falling while walking towards the SBS building for a radio show recording. Sieun was seen losing balance and almost falling after twisting her ankle due to the large high heels.

Even before Sieun was seen almost falling, she was seen walking much slower than the other members and looking clearly uncomfortable. Therefore, many fans gathered to an online community to criticize the stylist who had dressed the girl group.

Netizens commented, "The shoes are so big for her, she might fall and hurt herself real bad," "The shoes are not that pretty," "Why did they ask her to wear that?" "The stylist should have given her shoes that fit," "The shoes don't even look good with her outfit," "Looks like clown shoes, lol," "That looks painful how her ankle twisted like that," "They could have gotten shoes that fit her, they should know her shoe size," "Omg, I wonder if her ankle is okay," "That's so bad," "She could have fallen real hard and gotten hurt real bad," "The size is really big," "The shoes don't fit her at all, why did the stylist dress her in those?" and "That's a bad stylist."
