On December 21 episode of MBC's television show 'Sing for Me' (literal title), Hyoyeon made a guest appearance.
Hyoyeon answered, "We have been pretty good for the most part, so there weren't anything big in particular, but there was a small issue with our outfits in the past."
She explained, "Everybody wants to wear prettier stage outfits, right? It was the same for us. We would scan all our outfits, and be like, 'I want to wear that one!'"
She laughed and continued, "The one who wouldn't give up until the end would win, and get to put on the outfit they wanted."
Hyoyeon responded, "Oh yes, it is like that now. For a while after we made debut though, we chose our own outfits. Each of us would tell our stylists what we wanted to wear. But some of us wanted the same one, and our stylists couldn't listen to all our opinions."
She went on, "So, we changed the system―they decided for us. These days, we don't know what we are wearing before we arrive at the broadcasting station. It's so much better this way!"
