Things that used to be cool/trendy

Ok, searched but couldn't find any threads (no doubt some kind soul will just love to price me wrong though) so if there's another thread similar, apologies in advance!

Just looking through a few pics from about fifteen years ago, laughing at the hair cuts on us (remember the middle shade/curtain hair do on lads?) Wearing our Levis 501'a, Puma runners with the massive tongues sticking out above our Jeans like cricket pads! Back then we prob thought we were the dogs gonads, and it prob was the fashionable thing at the time.

A few other things I can think of that had their day of glory is:

Going to the roller disco!
Naff jackets (cringe)
Leather ties
Rave music
Mullets
Bum fluff moustaches
Lo-Lo balls
Lines shaved into your head (Jeez what thirteen year old lad at school didn't think he was hard as fcuk cos he had an arrow shaved into the head lol?)
Wearing football Jerseys to night clubs (what were we thinking?)
Lads perming their hair,
Girls perming their hair too!
Leg warmers
Calculator watches (ten plus fourteen? Ah that's easy!/five mins later, pressing tiny buttons to give the wrong answer Lol)
Learning to line dance cos it was the 'in' thing at the time (not me personally)
Grey leather jackets (shudders)
White socks with black shoes (bonus points for suede shoes)

Jaysus, I could go on all day.

What can you think of, that at the time was cool /trendy, but looking back you looked like a right tít, anything from an item of clothing to an activity our possession you had.
