I've never missed mine once.

It was a grim set of items:

• Black trousers or skirt. Trousers had to be "regular" cut, which meant nothing skinny, and anything too tapered, too tight or too short would have you sent home. Basically you could get away with bootcuts or wider straight leg trousers and that was all. Skirts had to be knee length, again anything too short and you were sent home. But no one wore a skirt for some reason, it was like an unspoken agreement. No one wore a skirt.
• White shirt "regular cut", which meant nothing fitted or with darts etc. Men's shirts, basically. Undo your too button and you'd be given a "pink slip". Three pink slips and you got a detention. Untucking your shirt also earned a pink slip.
• School tie. Wearing it too loose, too tight, too short or with a overly large or small knot would earn you a pink slip.
• Black school sweatshirt bought from the school uniform supplier. Taking it off without asking permission would earn you a pink slip. Even if it was hot and you were walking between lessons, apart from during the summer term when you were allowed to remove it. Anything except the sweatshirt from the supplier would get you sent home.
• Black leather shoes.
• Black or white socks.

I ended up with such a complex about how I looked after putting up with those rules. Spending 5 years in a lumpy sweatshirt and men's shirt that don't fit, with a pair of bootcuts trousers that were too long (petite ranges weren't easy to find locally ~10 years ago, and all the children's trousers locally were grey or navy blue to hit school uniforms for the local primaries so my only options were women's black trousers that didn't work on me. I was only 4'9 or so when I started secondary school, and by the time I left I was - and still am - only 5'0)

There wasn't really anything I could do within the rules to make me feel better about it either. I wore some skinny H&M trousers that I cuffed to the right length before they brought in mandatory morning trouser inspections (for the girls only. Naturally.) and my skinny trousers were quickly pulled up and I had to return to unflattering bootcuts that I couldn't turn up so dragged on the ground.

It only continued getting worse after I left (things like regulation polo shirts bought from a specific supplier in the summer term) and, coincidentally, the more they obsessed over the uniform the more the grades and other standards slipped until it went from being of Ofsted "good" with 62% GCSE A-C when I left, to bring Ofsted "inadequate" with less than 50% GCSE A-C several years after I left (my grandmother lives near the school so I still get the gossip now).

There was nothing redeeming about my school uniform. I've not worn a white shirt once in the 10 years since I left. Nothing made me happier than the fact my school didn't have a sixth form so I had to go to the local 6th form college instead to do my a levels, and they didn't have a uniform.
