I have just picked up my Dd from school and was pulled aside by her class teacher asking if dd could make sure she keeps her vest on for PE.
The reason she gave dd is that she is taller than the rest of the class(she is) and thats why she should 
Now I know she has started to develop small buds on her chest and I have asked her if she wants to wear a vest previously but she never seemed fussed plus she gets hot easily.
Neither has she complained of them hurting or rubbing, so Ive left it so far.
Aibu to feel irritated by this and surely if they feel so strongly about this they should issue out a letter to all parents to ensure every child should do the same?
