What's up with the katseye drama?

I wasn't that huge of a fan but I liked some of their music and their diversity in the group. Recently people are complaining that the clothes they were wearing for the new song pinky up is too revealing and how yoonchae just turned 18 and these clothes are way too sexual. Imo I think people are babying idol groups too much....showing concern is fine but I genuinely do not see the problem, they aren't just wearing strings as clothing and I like their outfits and don't see why people are acting like they're having some strip show with their private parts out. And yoonchae's fit isn't even that sexual? It seems fashionable and looks good on her. I don't see them uncomfortable in those fits so why? I get they began wearing more revealing clothes after gnarly became popular, but they don't seem to feel bad wearing it and kind of feel like they aren't bothered with it too.
