I see what you’re saying. But IMHO it depends what you think school is for. And what you think respect is.
I was at school during punk, when people like Vivienne Westwood were encouraging us to challenge the status quo, e.g. about how women should dress. Later, so did (Lee) Alexander McQueen, with his 90s bumster trousers with arse cleavage. They both respected their environment: British tailoring, tartan, Victorian gothic etc. But also subverted, pushed the boundaries and challenged. And are now two of Britain’s biggest brands, worn by Royalty, making millions, employing thousands.
I could say the same for music, art, science at school. So many British scientists have pushed the boundaries. I believe schools should be creative places, where people can show up as themselves and explore and innovate. Not places where you have to strictly conform and be regimented for the sake of it. Literally, uniform.
Respectful, yes. Considerate, yes. Kind, for sure. But conformist, no.
And in school girls should feel free to dress how they wish, without being concerned about what men think of them - or what they might do to them.
But depends what outcome we want education should achieve.
