What I don't understand is why some girls wear those skirts SO short, that they're literally ABOVE their arse cheeks? Seen it many times. A girl walking, tight lycra skirt, arse half-visible hanging out. What's the rationale behind it? It is comfy? Pretty? Sexy? Cool? It just looks sad, sleazy and ridiculous. I myself wore minis in my teenage years and still do, you can wear a mini skirt which is still edgy/cool/whatever and it covers your arse at the same time, it doesn't have to be a choice between uber-micro or dowdy matronly 40s job.
Mum's a teacher (private school abroad). Pupils have to wear blazers (not in hot summer), but the rest of the outfit is completely their choice. Any kind of clothing, footwear, makeup allowed. I've seen photos. All the pupils are in various cuts of jeans (mostly straight or wide leg/baggy), simple comfy tops and trainers. Pretty much the same they wear on weekends + blazer. No 'underage hooker chic'. Everyone's comfy and happy, no skirt measuring, no angsting over bog-standard black shoes being 'too trainer-y or not'.
And I know it's difficult to believe, but generation after generation of these kids grow up, find jobs, work and somehow still manage to wear even the strictest of uniforms, if needed.
