Older boys aged 16+ School Dress shorts

[NCScout]

I am just wondering where people buy their older boys grey school shorts from please? They seem to stop at age 14. I need age 16 and possibly 18.

Also, Next used to do a plus fit school shirt but I can’t seem to find these anymore. Have they stopped doing them?

I doubt you'll be able to buy them but you could get trousers altered into shorts at any alterations place.

I suspect getting trousers shortened might be your only option, I don’t know anywhere that wears school shorts beyond primary years.
