I know school uniform is something seen as sacred by many people in this country. It's become a given, that children who wear an expensive uniform behave better and achieve more academically than if they were allowed to arrive in a pair of jeans and a sweat shirt.
Travel through most other European countries and you see exactly that, children going to school in ordinary clothes. Yes yes, I can hear the outcry from some, who will suggest that a uniform ensures all children look alike. No they don't. The poor children will have one item of each uniform piece (if they're lucky), their parents are less likely to have the wherewithal to wash and dry uniform overnight so by the end of the week they look bedraggled whereas the better of children continue to look ok.
What's wrong with a pair of jeans/jogging bottoms, plain trainers and a T shirt, plus sweat shirt. Nothing is wrong with it and it's inexpensive and easy to replace when the little ** lose it.
