A seven-year-old boy in Tyneside has been told to change his spiky haircut or he can't go back to school.
Connor was given the spiky new look by his dad, who's a hairdresser, but the school says it's not allowed.
So is there anything you're not allowed to wear for school?
Are there any hairstyles that are banned? Do you have to wear certain colour shoes? Or are there other rules about your appearance that drive you mad?
Maybe your school is more relaxed, and when it comes to uniform anything goes!

James, 13, Swindon, England
"On our tie we have a crest, and we have to have it showing, we HAVE to have our top buttons done up, we HAVE to have our shirts tucked in, we HAVE to wear our blazers unless we have 'permission' to take them off, and we HAVE to wear black shoes. Not to mention the PE kit... I think its all a bit pointless personally!

Sean, 11, London, England
"I'm not allowed to wear my own clothes, because last year the head teacher made school uniform compulsory. At the time, I thought it would be better, because it would make us look smarter and it would be a change. But now it's so frustrating, because when you have your birthday, or when it's Christmas, and you get new clothes you can't make good use of them and wear them to school. But there are a number of reasons why we need school uniform and I suppose there is a point in wearing school uniform!"
Lucy, 11, London, England
"At my school, the girls can't wear anything shiny, or sparkly."
Sara, 11, Warrington, England
"I think if we are allowed to have different hairstyles and shoes, why can't we wear different clothes ?"

"My head teacher usually goes easy on school uniform."
Millie, 9, Reading, England

"I find it really annoying that our uniform is all black with a bit of white. It looks like we are going to a funeral."
Emma, 12, Cardiff, Wales
"Our school uniform is soooo slack! All we have to do is wear the school top and no high heels! I hate it because I get teased about what clothes and shoes I wear to school. When I first came to England I thought they were having a party because of the clothes they were wearing; pumps, fancy skirts, jeans, etc. I WISH we had strict uniform!"
Isabel, 10, London, England
"That's stupid, it's Connor's hair, it's none of the school's business. He just made it spiky, it's not an offence."
Saadia, 11, London, England

Sabrina, 11, Middlesex, England
"I think that some schools are being too strict and some older people in the years get to wear whatever they want but if we copy we get told off for it. I think all pupils should get treated the same."

Chantelle, 12, Sunderland, England
"I think that some schools are being too strict and others are being lazy and letting kids get away with things. Who knows right or wrong."
Suzanne, 12, Middlesex, England
"We have to wear black shoes which is a pain because I can't find non-leather shoes to wear to school. We can't have spiky hair which looks cool and we're also not allowed to dye our hair non-natural colours so we have to dye our hair back fast after Halloween."
Madison, 12, Gwent, England
"We are not allowed to wear our fleeces indoors. Last year we were allowed to wear whatever we liked but now it's RED uniform. It used to be blue!

Tatchiana, 11, Rochford, England
"We don't have school uniform, we can wear what we want and the school encourages us to be creative with what we wear."
Caitlin, 13, Oxford, England
"In my high school you have to have your tie seven stripes and tuck your shirt in. Most people don't do that including me but the teachers never say anything so we get away with it!"
Arooj, 12, Lancashire, England
"We aren't allowed unnatural coloured hair, we can't have more than one piercing (and that piercing has got to be in our earlobe), we've got to wear our school uniform, we can't wear zip-up jackets (even if they're in our school colours) and your ties have to be the right length if you wear one. Our school is tight!"
Madi, 13, Gwynedd, Wales

Fran, 13, Tunbridge Wells, England
"My school doesn't let us wear jewellery because it can get lost, stolen or it might fall off. We especially aren't allowed hooped earrings. We also aren't allowed flip flops."
Nahida, 10, London, England
"We can have our hair however we want, but we can't wear whatever we want. Some people still manage to wear different coloured belts or different types of jumpers, even if it's not allowed."
Ellis, 13, Suffolk, England
"Our school won't even let girls have trousers. They make us wear our hair up, we are not allowed make-up, our ties have to be eight stripes long, our shirts have to be tucked in, we have to ask to take our blazers off and if you go against one of these rules you have to scrape chewing gum off desks. It's not a moral outrage to be an individual. I think schools should let us be open-minded and let us have a choice as to what we wear, how we wear it and what colour it is. They always encourage us to make choices, but it doesn't seem like they care. THEY ARE STUPID RULES!"
Kathryn, 12, Cheshire, England
"At my school, we all have to wear a tie, a blazer, a shirt, black trousers and black shoes. I think we just look boring."
Daniel, 13, Cumbria, England

Bobbi, 14, Bognor Regis, England
"Don't get me started! There are so many things we aren't allowed; make-up, jewellery, badges, dyed hair, bags have to be A4 sized, chewing gum, earrings, trainers, piercings, wristbands... I could go on for ages!"
Rebecca, 13, Kent, England
"We have to wear a uniform and blue/black shoes, and on Halloween my friend wasn't allowed to wear a Halloween scrunchie!"
Lu, 10, London, England
"In my school we have to wear the right shoes. We have been told that we can't wear 'ballet pumps' because they are inappropriate, but loads of the teachers wear high heels and things that cause way more damage to your feet!"
Zara, 13, London, England
"We are not allowed to wear gel in our hair and to have our hair down. It needs to be above your shoulders."
Lauren, 11, Bracknell, England
"Fancy hair-bobbles have been banned! But they keep your hair up just as well and they allow a bit of 'you' on your uniform."

Rosa, 9, London, England
"That's just bang out of order. He should be allowed to have whatever hairstyle he wants. They should let him go back to school anyway, otherwise he won't get a good education."
Alex, Nicole and Becky, 9, 9 and 13, Kent, England
"I don't have to wear uniform at all as I am home educated, but I prefer to wear my hair in a ponytail to keep it out of my face while I am working. I think that children should not be allowed such hairstyles for school though."
Olivia, 11, Lancashire, England
"In our school we can wear pretty much what we like. As long as it's not like the hair in the picture!"
Bethan, 14, Gloucestershire, England
"My school are big on jewellery. They simply don't allow it unless it's religious, but they aren't so tight on hair so we can make ours as crazy as possible!

Melissa, 13, West Sussex, England
"You're not allowed to wear jackets inside, or leg-warmers or trainers, and you always have to wear your blazer. It's rubbish!"
Caitlyn, 13, Glasgow, Scotland
"My school is really strict when it comes to dress code. We are not allowed to wear trousers, your tie has to be to your waist, you can only take your blazer off with permission and then you have to wear it in the corridors even in the summer. Boys cannot use hair gel or have their hair shaved or dyed. Girls cannot wear earrings or make-up or dye their hair. If you are found to be wearing make-up they make you wash it off. If boys turn up wearing gel they are made to wash their hair. We have uniform inspections regularly. I don't disagree with my school's uniform rules because it shows discipline and stops some bullying when image is a big part of growing up."
Beth, 13, Staffordshire, England
"I've heard our head teacher say we must wear grey or black trousers even though some people have worn jeans before, so I just don't get it!"
Brad, 9, Rotherham, England
"You should be able to choose your hairstyle. Sometimes your teachers come into school with weird hairstyles - you should be able to send them home if they can send
Amy, 9, London, England
"We aren't allowed to have any jewellery or make-up. We are only allowed one ring and a pair of studs. At the beginning of the year, we were only allowed to wear hair bobbles and hair bands in uniform colours and white socks, but now we just wear any colour socks and hair bands."
Jess, 12, Kent, England
"People can have any hairstyle they want, but it can't be sprayed with hair dye."
Rosie, 11, London, England
