I've seen that before too , it is pretty shocking.
As shocking as things like this:

We live in a world where very young children are being exposed to sexuality and the notions of looking "sexy" or "attractive" are being picked up on at increasingly younger ages, it's wrong but this is not a new thing.
Babies in heels makes no sense at all. Toddlers trying the heels of their mother, or asking a princess outfit with plastic, slightly heeled slippers is a bit different.
Birthday parties for primary school girls, where they can learn pole-dancing is horrendous imo, and happening.
My older sister used to dance and was ins hows at the age of 7 so she was wearing full make up at a very young age there of course is nothing wrong with that nor is there anything wrong with a mother and a daughter doing make up together.
Teaching girls at that age IS wrong on one hand but I suppose the elements on what the emphasis is on can make a difference.
E.g , If the emphasis on pole dancing is to look sexy and etc yes that is wrong
if the emphasis is on it being good exercise (it's supposed to be a brilliant way to lose weight apparently
) and a dance form or w.e I suppose that isn't as bad.
That ones a bit of a trickier subject I guess.
