Sorry, haven't RTFT, but I would probably be more sympathetic to the idea that this was to tackle inequality if
a) schools stopped booking "educational" trips costing several hundred pounds (some a couple of thousand), and
b) teachers weren't parking everything from an old Ford Ka up to a top of the range Mercedes and Mustang in the car park
Schools banning stuff like this will just make some kids want them more; many kids who had never really heard of them suddenly know what they are and will now want one. It's almost as if the teachers and media were acting as free advertising...
Pyrenex and Canada Goose kids coats are going from about £20-30 second hand on ebay - cheaper than the brand new Regatta jackets (from the outlet store) I bought my two when they deigned to wear stuff I bought them.
