What do you think about young girls enhancing their sexual attributes?

This is a take-off from a question about tramp stamps on girls. I want to take this into a more general discussion.

How do you feel about a girl, say ages five through twelve, adorning herself with decorations that are implicitly or explicitly sexual? Is it cool with you that a girl of that age points out her sexual nature, and invites people to treat her more as if her sexuality were more important than anything else about her (assuming it does that, a point which some of you may wish to disagree with)?

I’m talking not just about tattoos, but about wearing makeup or dressing in alluring outfits or bikinis such as girls do in beauty pageants and the like. Even further, do such pageants focus male attention more on the girl’s sexuality, and away from their other attributes, thus attracting sexual attention from males?

Is this just a form of play (or semi-professional play) that is perfectly acceptable? Or is it a form of play that leads people to form a narrower view of the girl; a view that is focused on her sexuality? If so, is that bad?

Or can we consider it merely play, and that play with sexuality is appropriate, since all play is practice for being an adult, and women do use their sexuality when they become adults. Indeed, for some, sexuality is the primary attribute that they use to make a living? Thus, are we turning girls towards the sexual professions when we let or encourage them to play with enhancing their sexual allure?
