It is a pity that the school governors do not think about parents' budgets when they make these decisions.
One of my nephews, who had so many problems (ADHD, on the autistic spectrum) was at a secondary school, where things were already not going very well, and then the school became an academy and introduced a new uniform. Everything went down hill after that - he would not wear it and was in constant trouble.
Now, clearly he was in the wrong for not wearing it, but it just became a focus for all his frustrations with a system that had failed him. And this is the problem with a strict uniform policy - it is a good way for troublesome children to express their dissatisfaction and becomes a big bone of contention when their educational progress and happiness are so much more important.
And I hate to see teenage girls dressed like "little men" - black trousers, shirt, tie, blazer - it's a bit weird. And the big-busted girls look dreadful. There is something slightly kinky about it - and it is unlikely to make them feel comfortable with themselves, which is so important at that difficult stage in their lives.
