It is 25 years since I was a teenager and 29 since I was in high school, so teenagers might be different these days, but I doubt it.
Why did we roll up our skirts so short you could probably see botty-clackers, arse-biscuits and gussets...
Because we could.
Because (we thought) it made us look very sexy, grown up and clever.
Because (we thought) it made us look more attractive.
Because we were made to wear a uniform and therefore the only way to try and show any personal identity was to roll up skirts... add in a pair of over the knee black socks, a jumper or untucked shirt that comes down to the same level as the skirt and you can look like you're wearing a shirt and a pair of stockings...
In essence, we wanted to look like sex workers and glamour models. Or at least, like everyone else. (Despite at the same time NOT wanting to look as the school uniform guide wanted us to look... because who wants to all look the same UGH..)
We'd also compete to see whose hair could be the highest, whose odd fringey quiff bit could be the highest and whose perm could be the massivest...
Teenagers do not have the decision making and reasoning skills adults do. Which is why adults make the rules.
Schools should ditch skirts - give them a variety of trousers - unisex 'work place' trousers, joggers or leggings so no one feels they have to squeeze into something that reveals lumps and bumps if they don't want to. Make them all have to be black. End of botty flashing gusset waving problem.
