God, I left school in 1990 so all of these trends are bringing back some painful memories, I think I wore everything mentioned.
Lots of tiny t-shirts with cute prints on (they were cute then - I'd look certifiable in them now). Short skirts, opaque tights or flared Levis and daps, Puma, Adidas etc. This was particularly prevalent during my uni years, which coincided with Brit Pop.
Chiffon shirts (oh the sweat).
M&S mens' cardigans and jumpers over leggings with DMs.
But for day to day wear while at college and uni, leggings and hoodies or lumberjack shirts. Which is exactly what sixth form and uni students wear today. I work at a secondary school and it's like the exam hall has been frozen in time during A levels.
Tiny backless tops and no bra.
I've kept a few things for my daughter but I'm starting to wish I'd kept a lot more, like my ballet tops and wrap skirts as it sounds like I'd be cutting quite a fashion dash on the school run.
