@MarieDeGournay : The best thing of all was that the first uniform included a tie, which was deeply thrilling for little gender-questioning me
(the emoji is still there as I type but it doesn't appear in the Preview?)
Now, I have fairly strong opinions about girls wearing ties. When I joined my last school (1992) there were girls only in the sixth form.
All sixth formers, then and now, were meant to be in "smart business dress," which meant a shirt or open-necked white blouse, optional plain v necked jumper, dark jacket and trousers or skirt.
All the boys wore/wear a tie: which one might signify something (house or school colours, prefect etc) but I've never paid a great deal of attention to that.
Soon after I joined they started taking girls in the lower years, (which probably helped me to be appointed), and their uniform was discussed. There was a committee of staff members who proposed it should be the same as the lower-school boys', except with a distinctive pleated skirt instead of grey trousers. This meant it included a school tie.
I did object (there weren't many other female staff at the time, and I was part-time) but it went ahead probably because one of the younger female staff, who was on the committee, often wore a shirt and tie herself.
(As far as I know she was not at all gender-questioning but such things weren't on my radar 30 years ago. She was married, a rower, and left to spend the rest of her teaching career at a very famous boys public school).
Some years later the uniform was discussed again, and ties for girls were discontinued.
(In the summer term everyone can wear the school polo shirt, if they so choose.)
