They still kicked off about it but I went down and kicked off more and they eventually relented and agreed dd could do pe in plain black leggings but not to make a habit of it
I do wonder what magical powers that schools name written down the side of them has over her pe performance
I swear they create problems so they can flog you the over proved solution. Even when appearing to be reasonable amd allowing alternate sources they aren't.
For instance base layers. Must be plain black. All the cheap supermarket ones have coloured piping. It goes under the clothes. Most thats gonna be visible is part of the arms. Not to worry school.shop sells them....
No hoodies. They survived all primary school with a hood on their tracksuit top suddenly that 6 pound plain black.or navy hoody in tesco you usually buy is no good.that 1 hour twice a week , be anarchy if they had a hooded tracksuit top 
School supplier to the rescue
School jumpers. Despite everywhere from asda tbrough to John Lewis selling a range of red, blue ( navy and royal) green, purple, black, grey crew neck amd v neck jumpers that would be perfect for under the blazer or instead of, even if no logo is permitted you can garuntee it will be some bizarre hybrid shade of grey/black that you cant get anywhere besides....any guesses where ????
And sports leggings must be plain black with no logos. Better sharpie out that Nike tick. Because they make damn sure that the entire range of easily amd cheaply available sports direct leggings will somehow be unsuitable. And regular plain black leggings sold everywhere well...seems the shine and the spandex must have magic powers because they aren't allowed either. See through dance tights at 16 quid a pop from from school shop it is then...
And its hardly a choice of pleated school skirt if the pleats now have exact measurements. Who knew 5mm could render a sainsbury skirt so useless...not to worry if the one branch if next that sells the only acceptable high street skirt is rammed with every school girl in the town and out if stock they will happily sell you a skirt with added delivery fees on top. Problem solved.
