My DD's secondary school have had an overhaul of their uniform policy. They have said that the new skirt is one specific type only and that it must be purchased from their online supplier or from a specific local shop. It costs £20.
The skirt itself is not compulsory, girls can choose to wear trousers but boys cannot choose to wear the skirt.
The other one-supplier uniform items are the PE top and the blazer.
It seems to me (as someone with no legal background at all) that there must be some discrimination law around making a single sex item only be allowed to be bought from one supplier when trousers etc can be bought cheaper from a supermarket.
I'm only bothered as a point of principle, the skirts were getting ridiculously short but I do think a general style would have been better.
Do I have any grounds to complain?
