I turned 10 in 1990 so the 90s were my teenage years.
Television:
As a young tween/teen, it was Maid Marian and her Merry Men, Byker Grove (ahahahahahaha), Grange Hill, Moondial, Simon and the Witch
As I got older I remember Queer As Folk being a bit of a shock (watched it with my Mum), the gay kiss on Brookside, This Life
Clothes:
I wore what I liked tbh and didn't fit in but there were some very distinctive groups. One wearing polyester tracksuits with poppered legs, the combat trousers/vest brigade, some girls tottering about in baby doll dresses and heels, nasty Sweater Shop jumpers and clumpy Kickers shoes all over the place, Army surplus jackets worn over dresses with massive boots and striped tights.
Everybody reeked of White Musk or some weird concoction from the local herbal store (moss with overtones of mud iirc), people still shopped in C&A or Tammy Girl, lots of big dangly, ethnic type earrings and heather shimmer lipstick.
Magazines had pictures of 16yo 'hunks' with curtained hair, shiny abs and big, baggy jeans with 7 inches of white underwear over the top. People would titter over More mag's Position of the Week and pass round illicit copies of Judy Bloom's Forever.
Weird plastic dummies had a rebirth and everybody was obsessed with flavoured lip balms.
Music was Terrorvision, Nirvana, Oasis, Blur, Reef or awful boy bands with choreographed moves. I remember Four Non Blondes and Ace of Base being massive too. Bryan Adams and Wet Wet Wet at No1 for a gazillion years. Mr fucking Blobby. Whigfield. Um, Going Live and SMTV.
Friday nights you'd try and stay up late to watch The Word but be asleep and drooling by the time Davina McCall's Streetmate had finished. Eurotrash was always on and always weird. Saturday nights was Gladiators and checking The Pools. Pop man came on Sundays and we played on building sites even though the scary public info films warned us not to.
And Burton's Fish and Chips. I miss them. More than is healthy.
