There are girls who roll up the waistband of their school skirt as soon as they have left the house, even I did, short skirts were in fashion, but my parents would still have been horrified.
A glimpse of little girls knickers showing etc is not an invitation to sexual bullying, unwanted attention or whatever, nor should a girl growing secondary sexual characteristics sooner than her peers be an excuse for an adult or older child to behave inappropriately towards her, but I think that is not what lovebunny has picked up on.
This is not the same as the young girls who leave home in clothes that mimic the codes of dressing that are used by adult women to advertize sexual availability - forget the kneejerk response of 'I can wear whatever I want without being groped'! I am referring to an age inappropriate way of dressing that must almost definately condoned by their parents - or the child would not get out of the front door. Tight lycra and shirt buttons bursting open as a style of dressing does not fit into my view of how children should dress at school, it is inappropriate in that context, and inappropriate for a young child.
Some very young girls use dress codes and behaviours that are seen in our society as adult invitations to sexual interest by men. This may be a sign of 'grooming' and inappropriate relationships with adults outside school. Children, certainly those under 16, should not be using adult dress codes to make overt displays of their sexuality at school. We live in a hypersexualised culture and have become far too accepting of this trickling down into the social lives of children..
Send me a biscuite, I don't care. I do care that kids can grow up without being pressured into sexuallly charged environments they are not yet ready for.
