Talking from a TA point of view, I would say trousers are much easier to wear, in cold weather , than tights. It depends how easily and quickly they can can put them back on after PE. It can take a long time to get ,say,10 children’s tights back on!
As for hair, I don’t know how these girls have such elaborate hair-dos!! My own daughter , 17 years ago, had hair down to the back of her knees (when brushed out) , but I only ever did one thick pony-tail plait….didn’t have time for anything else!!!
What bothers me more is the current trend to dye young children’s hair - either ‘natural’ colours or bright - this is totally baffling to me. Why would you do this to a young child?
I can sort of understand the more mature Year 6’s wanting to be a bit different, ( though most won’t be allowed at secondary school) but 5, 6, 7 (+) year olds?
But there you are… I’ve never dyed my hair, or had tattoos or piercings other than earrings, because I don’t get why people want to do that to themselves. My daughter , however, ( now an adult and a teacher), has all these things and I still don’t understand, but I just nod and say it looks very nice….
