Chaeyoung, a member of Twice – one of the most globally successful K-pop groups – has apologised after wearing a T-shirt featuring a swastika.

The 23-year-old’s T-shirt featured an image of Sex Pistols bassist Sid Vicious wearing a swastika logo. She posted a photo of herself wearing it on her Instagram account to her 8.6 million followers, but soon deleted it, replacing it with an apology. “I didn’t correctly recognise the meaning of the tilted swastika in the T-shirt I wore,” she wrote. “I deeply apologise for not thoroughly reviewing it, causing concern. I will pay absolute attention in the future to prevent any situation similar from happening again.”

It was the second clothing-related controversy for the vocalist this week, after she performed in a crop top emblazoned with an American flag in a Q shape and the slogan “where we go one, we go all”, a phrase used by conspiracy theorist network QAnon.
