A mum was left furious after her daughter was threatened with a detention at school due to her skirt being too short.
The daughter of outraged mother Tammy Humphreys was handed a note and warned that she could be kept back after classes if she wore the outfit again.
Her skirt, which she wore on her first day back at Ysgol Eifionydd school in Porthmadog, North Wales, was said to be too short as it rested just above the knee rather than being knee-length as the school's uniform policy strictly states, reports Birmingham Live.
Tammy stated she "couldn't believe it" when her daughter told her she would be sent to detention if she ever wore the skirt again.
She said it was the exact same type of skirt her child had worn the previous school year, only the next size up.
Tammy shared a picture of her daughter in the school uniform she had worn that day, which received more than 100 incredulous responses on Facebook.
The Year 8 pupil was among 18 students at the school given a detention warning over their uniform on the first day of the school year in England and Wales.
Tammy said: "My daughter returned from her first day back in school on Monday and told me she had been given detention for her uniform, which didn't make sense to me as she looked completely fine.
"Then I found a few other pupils had been given detention for the same reason - with one pupil warned for wearing ankle socks.
"Some of the others, I'm told, were given detention for wearing piercings, too much make-up and trainers, which is more understandable.
"But I can't see the issue with the uniform my daughter had on. She had black shoes, plain black tights, a jumper that's slightly big for her and a skirt that sits at a reasonable height just above the knee."
The letter Tammy received said her daughter would be in detention after school on Wednesday until 4.30pm if she was warned twice more about the skirt.
Headmaster Dewi Bowen said the detention period had now been shifted to lunchtime on Wednesday and would only apply to pupils who received three "strikes" over their uniform.
The school's uniform policy prohibits "unacceptably short skirts" as well as "jeans, leggings or tracksuits" and "trainers or shoes with white coloured marks, logos or soles".
False nails, make-up (with some exceptions) and unnatural hair colouring are also prohibited.
However, Tammy - and many others on social media - disagreed with the assessment her daughter's skirt was "unacceptably short" and said she would not be changing anything about her daughter's uniform "because it's clearly fine".
"She wore the same type of skirt throughout last year and there were no issues - it's ridiculous," she said.
"I've been sent a letter and an email saying her uniform is not correct as her skirt's not the right length and that she'll be sent to detention if it's not changed.
"I've refused to sign that letter and told them they can take her shopping if they want."
Mr Bowen said: "Ysgol Eifionydd has a school uniform policy in order to ensure pupils have a feeling of belonging and to ensure an ordered and calm atmosphere.
"In April, when pupils returned to school, we concentrated on ensuring the pupils were comfortable and supported.
"Since returning in September, as a school we felt it important that we return to normal including ensuring the correct school uniform.
"All parents have been informed of the school uniform rules in two letters before the summer holidays as well as a reminder before pupils returned on September 6.
"This explained that breaking the school rules are dealt with in accordance with the school’s disciplinary policy and that of course, when pupils conform then any sanction is rescinded."
