School Uniforms - how many of what do you buy?

[Trillian]

Mind you though, I get two years out of the shirts, shorts/skorts/skirts and jumpers. The only things that I have had to replace yearly are the trousers because it's so noticeable when they grow LOL. DS has had his sports coat since Kindergarten - it was a bit big on him then and now it's a bit small, but still does the job and he's been at school for 4 years now so some of the stuff you will get loads of use out of unless he's really hard on gear and gets it too stained etc or if he grows too much.
