I remember being teased mercilessly in grade 5 because of my hairy legs and armpits, but my mum would not let me shave them. So if my daughter wants a leg wax in grade 6 (and has the hair to need it) then yes, she can have it.

Fake nails and tans I am not so keep on, because it is not something I do myself. But if these girls are just trying to recreate the look their mum has then I think it's fair enough. kids love to imitate their parents and feel grown up, I don't see the harm.

Revealing dresses I would draw the line at though, I prefer modesty on children whilst they are still young and innocent.
