Early 90s:
Short black lycra dresses with opaque black tights and DM shoes (oh to have the figure I had on my 18th!)
Long floral button through dresses/skirts with chunky lace up boots or DMs. Often from River Island when it still sold such things and the shops were decorated in a Deep South/Mississippi River Boat style with lots of antique accessories and wood panelling
Long waistcoats with only a bra underneath and fake Levis 501s
Flasher Mac from charity shop 
Bodies and jersey tops
Thin silk scarves worn choker style
Long wrap skirts
Floppy velvet hats
Jewellery I'd made myself
Chunky knitwear
Sweater Shop and Benetton
Disclaimer - I was a student for most of this time so had neither money nor taste.
Later 90s:
Short skirts and clumpy heels for work
Smart black suit with no shirt underneath for evening work dos
Black Chelsea boots
Pinafore minidress with knee high boots
Retro Adidas t-shirts and trainers or anything else the Britpop crowd were wearing
Baggy jeans
Slogan t-shirts - had one particularly tragic one with 'Born to Party' printed on it
Skinny fit tartan patterned trousers (why???)
