So DCs school has a new headteacher coming in in September. The uniform has stayed the same apart from the blazer getting a makeover and becoming a bit posher 
However, the uniform used to be fairly optional as long as a blouse/shirt, school jumper and black shoes/trainers were worn you didn’t have to wear the blazer. Now the new head has sent booklets home to all families with information.
He’s changed the skirt rule. The former head was a proud feminist and said girls and boys can wear skirts or trousers, it was totally up to them and the skirt used to be fine as long as you couldn’t see their underwear! I would say 99% of the students really did respect this rule end wore suitable length (for school) skirts.
Now the new head has abolished trousers for girls and skirts for boys. Girls skirts must come below the knee and if seen higher, an hour detention is the immediate punishment. His reasoning? ‘X is a professional site in which all students must aspire to learn and we must all endure we don’t distract other students by our attire’ He’s evidently stating that shorter skirts distract boys and that girls must be responsible for boys behaviour.
I also have a DS at the school and it says on his booklet it states that if boys are seen with their trousers hanging down so underwear can be seen, they are put in for a 45 minute detention?
Aibu to think this is blatantly sexism and to think about complaining? I’m not usually one to get on the schools’ back as I know they’re underfunded etc but this is ridiculous in my eyes and the eyes of DDs and peers.
