*The point you don't seem to understand is that very often the knickers that are sold for girls don't always cover the area. If it was covered there wouldn't be an issue. There is also the issue that we aren't just talking about 4 year olds, some girls at primary school will be 11 and already having periods. You might think it doesn't matter, many adults in school think it does.*
The point you don't seem to understand is that I am not saying that it doesn't matter. In fact I have said on more than one occasion that (IMO) the point is that girls (at any age) should have agency over what they wear and that trousers would be a more sensible option than extra clothing to keep them modest when wearing dresses.
You do seem determined to find something to pick up on in all of my posts, however - it started with you disagreeing with my comments about how girls were being asked to cover up to protect them from men - and has moved to you saying that I am not aware that modern knickers are sometimes more skimpy than gym knickers of old, and that many 11 year olds have periods. You move the goalposts each time.
I do understand - what I am saying is that it is the fact that dresses are not suitable for physical play that is the issue, whether worn at 4 or 14. That and the fact that if it were not for predatory men there would be less of a need for 4 year olds to cover up quite so assiduously.
4 year olds are usually quite unselfconscious about their bodies and will, for example, happily run in and out of the sea naked without a second thought. We do have to teach them that to protect them against predators this is not always a good idea, but (again IMO) a better way to achieve this is to dress them in appropriate clothing rather than to insist on inappropriate clothing with additional garments for modesty.
Being unselfconscious about your body on a beach is quite different to in the classroom. The issue in the classroom isn't to do with predatory males, female teachers don't like it and it isn't appropriate.
Girls should have agency within the limits of acceptable behaviour so if girls want to wear no knickers or skimpy knickers then it is reasonable that they save their agency for an appropriate time.
Mentioning girls in primary can be 11 and having periods was because you seem to bring it back to 4 years old and it isn't just about 4 year olds.
