DD (10yo) does swimming lessons at school. The rules are that girls must wear a one piece swimming costume and we have of course adhered to the rules and purchased one specifically for these lessons.
DD is starting to get to the age where she's a bit more self-conscious of her own body and at home, prefers a tankini which has short-like bottoms and a full length tight (i.e. not flapping about everywhere) top. We encourage body confidence where we can, but I also want her to feel comfortable and confident in what she wears. I therefore asked whether her preferred tankini would be acceptable for lessons and was told no, girls must wear a one-piece.
On the other hand the boys all wear swim shorts and a few of them wear swim shorts with swim tops - the UV type ones.
I assume they're worried about a 'slippery slope' or girls starting to wear bikinis if they allow a full coverage tankini, but what is offensive about a girl's belly button, when most of the boys have their belly buttons out and some of them are even wearing two pieces?
I realise this is a small problem in the grand scheme of things, but it has left me (quietly, in my own home) quite irritated at the double standards. AIBU?
