A question on school uniform

In regards to school uniform, my grandson goes to Ratton School.

When going back he needs uniform, and both places which sell them do not have his size.

In this climate when money and work is tight surely it should be possible to order normal trousers so he can have the right size (same colour and trousers just without name of school on the back) which is hidden under the jumper?

I am sure he is not the only child with this problem. A comfortable child is a learning child.
