That sounds about right -although at Dd2's school they have to wear tights (80s denier, all year) and are not allowed to wear knee length socks- but can wear ankle socks for about 2 weeks of the year. It's not a rule I see the logic of. It's to stop them rolling their skirts, apparently.
It doesn't.
No chance of anything sensible like P.E kit (but their kit is so ugly, she would rather wear full winter uniform than be seen 'in the wild ' in it
).
