The thing is, this is how a lot of kids at dance competitions will be dressing and they copy the dance style of the day, which, unfortunately, might include twerking. I hate seeing kids dressed like this but I am aware that I am projecting an adult mindset onto it - the kids just like the clothes and think they look cool and like pop stars, the vast majority won't grasp the sexualised aspect or be aware of the risk they face from paedophiles. That's the sad part, that it's not ok for children to wear what they want, or (for younger kids more I guess) nothing, or copy dance routines, however unsavoury, because some adults make it unsafe for them.
