Just occuring to me now: I don't think girls wear dresses at secondary school anymore, do they? I'm talking about your local comp not posh public schools where they'd've wheeled the boater out by now .
I am getting the impression that:
a) summer dresses no longer happen
b) the girls wear skirts and bike shorts for PE
c)blazers are disappearing in favour of sweatshirts!
I recall when you got in proper trouble if you weren't wearing the summer dress by a certain date, where you wore an artex shirt and green gym knickers to do most indoor sport- and where most gilrs uniforms included a balzer!
The only item in that list that was cast aside too quickly was the blazer. What a handy piece of kit! All those pockets!
