It's London Fashion Week so loads of top designers are showing off their newest creations in catwalk shows around the city.
But one designer has grabbed all the headlines by using models that are a larger size than the ones you normally see, although they're still thinner than the average woman.
Some people in the fashion industry says they use thin models because it makes their clothes look better. But others think people on catwalks should be shaped a bit more like the rest of us. So what do you think?
Do you think models are too thin? Would you like to see more "normal-sized" models on fashion runways?
Does it matter what size a model is or is it all about the clothes?

"Loads of people at my school want to be models and size zeros, so much so that sometimes they skip lunch. I think this is wrong. I'm not saying that all models should be big but why couldn't fashion designers have lines of clothing on the catwalk intended for a variety of sizes."
Aria, 13, Norfolk, England
"I think they should be within reason - not size 0, but not size 16."
Fiona, 9, Massachusetts, USA
"It doesn't matter what size a model is, they can be any, people that get models to a size zero are wrong. They upset others and it is setting a bad example to self-conscious teens too!"
Mollie, 11, Liverpool, England
"It really doesn't matter! Models can be any size, as long as the new fashion looks good."
Holly, 12, Wales
"I saw a shop advertising to models. They asked for girls aged 15-25, size 0-12! So if you were just 26 and size 14, which is perfectly reasonable, you aren't allowed to model. It's ageist and sizeist!"
Sophie, 11, Hertfordshire, England
"I think models should be skinny because everything would look good on them."
Sara, 13, Birmingham, England
"I don't think that all fashion models should be slim because it wouldn't be fair on the people who aren't slim."
Manashee, 10, London, England
"You should not have to be really skinny to be a model. They just have to feel good about themselves and not be worried about staying thin!!!"
Meg, 9, Renfrewshire, Scotland
"I don't really think it matters what size they are unless there not too big. I think confidence and enthusiasm matters more"
Elle, 11, Brighton, England
"Of course it doesn't matter. As long as the model looks good in the clothes she's wearing. If all models and celebs are size zero, children will want to be plastic and skinny. Nobody's perfect, so why judge people by the way they look."
Miranda, 10, Glasgow, Scotland
"It doesn't matter if a person is a size 2 or a size 12, that's the way they are. It isn't a good image to send out to younger children at all."
Callan, 12, Northern Ireland
"I think it doesn't matter, they should let all different shapes and size model because otherwise it makes larger people feel uncomfortable."
Mariam, 11, Glasgow, Scotland
"I think it's disgusting that size 12-14 models are PLUS SIZE!! What sort of image is that sending to young children?"
Emma, 14, Kent, England
"I think all women should be able to be models but unfortunately the size is much smaller than most women are, no offence."
Savannah, 12, London, England
"I don't think it's fair because designers only make clothes for slimmer women. Larger women may find it offensive. Anything from size six to 16 is okay in my view."
Rachael, 13, Manchester, England
"I think that models should be every size because it doesn't matter and it isn't setting a good example to kids is it?"
Samantha, 11, Scotland
"I think it is great to see a model who is not a size 0 and doesn't look ill, and they have proved that you don't have to be skinny to look beautiful!"
Grace, 12, Wales
"I think that models size eight to 14 are good for the catwalk because it shows girls all the right sizes, and also shows that the designer can make clothes for normal sized women. I think that size zero models should be banned from the catwalk!!"
Amy, 12, Manchester, England
"I think it doesn't matter who you are or what size you are to be a model. Just follow your passion."
Willa, 11, London, England
"It's ridiculous to set guidelines on how thin someone can be to be a model. Sure, very thin models are a bad influence, and there shouldn't be an upper limit. But there shouldn't be a lower limit either! Because we're all really short, all the women in my family are sizes four to eight. If I was stopped from being a model for being too thin, I'd be really upset and angry. It works both ways."
Noemi, 13, London, England
"I don't think it matters what size models are because people are different shapes and sizes."
Sinead, 9, Down, Northern Ireland
"No, it doesn't matter! Everyone's equal, no matter what they look like. You don't have to be pretty to be beautiful! People really need to remember that."
Hannah, 13, Shropshire, England
"Considering the normal size is around 14, half the clothes that get put on the catwalk won't look nice on anyone unless the models are the right size! I think it's silly saying that bigger women do not look 'terrible' if they are on the catwalk!"
Charlie, 13, Essex, England
"The models don't even look FAT. Using size zero models will put too much pressure on kids to look skinny and beautiful."
Fatima, 11, Leicester, England
"It depends, because if you are obese than it wouldn't look right but you shouldn't have to be a size zero to be a model."
Phoebe, 10, Kent, England
"All models are ugly anyway, just look at Kate Moss, UGH!"
Baxter, 14, Reading, England
"I think everybody should be a model because some people tend to refuse to eat until they get to be a model and they can get seriously sick!"
Rebecca, 11, Scotland
"I think that these models should just look like normal, healthy women when they go down the catwalk. Size zero models just don't look natural. There is already lots of pressure on young girls to look beautiful, skinny and to grow up too fast. Size zero models just make it worse as many girls look up to them and think that is the right size to be, which it's not."
Sarah, 12, Northumberland, England
"Not all girls are skinny, a size 12 is how girls should be - curvy. Otherwise all girls feel like they have to be skinny to be pretty when they don't. If someone dislikes you because of your size they're not worth the bother."
Emily, 14, Gloucestershire, England
"I don't think these fashion models should go to the trouble of trying to lose weight all the time. They should be happy with what they are."
William, 10, Barnsley, England
"I'm not very sure, to be honest. It would be weird seeing obese models but I also think models are FAR too skinny."
Becky, 12, Aberdeen, Scotland
"Well yes and no. No, because everyone is beautiful in their own way so size doesn't matter but yes, because some people who are skinny suit one style but people who are a little curvier suit another!"
Elaine, 11, Scotland
"Yes, it does coz then if they're really fat other people will say 'ooh I want to be like her' and they'll become fat."
Charlotte, 14, Leicestershire, England
"I don't think it actually matters, whether big or small, short or tall, you can still be fashionable, and that's exactly what the designers trying to show."
Ayat, 13, London, England
"No! Models give children like us the impression that we are fat if we are not stick thin, I think some of them look so unhealthy! You are beautiful no matter what your size."
Laura, 12, Glasgow, Scotland
"I think that the average size for a woman, 16, is far too big to be on a fashion show. I think the limit should be size 12."
Sumeeta, 11, London, England
"If a designer can't make clothes that look good on normal sized people he must be a pretty rubbish designer. I think bigger models will have a very positive effect because they set a more realistic standard for young girls. So many more people are likely to eat healthily and exercise to reach that target rather than being physically unable and getting depressed."
Sian, 10, Kent, England
"I think they should use even bigger models because it will show all women are equal and you're not special if you're size zero."
Taylor, 14, Wales
"Fashion designers should take a leaf out of Mark Fast's book! There should be clothes for every shape and size but not too skinny and not too big! Skinny models all the time just look unhealthy and ugly!"
Lucy, 14, Derbyshire, England
"No I think that it doesn't matter what size you are. Actually it's really unhealthy to be a size 0 because that can lead to death and they should ban models that are size 0 and only have models that are fit enough and starve themselves!"
Ayesha, 12, Leicester, England
"I think it does matter as if they are over size 12 then they can only wear a limited amount of catwalk clothes and still look good. I think that some models in the picture shown don't look good, yet if a model of size 8 wore it they would look a lot better."
Becky, 14, Wales
"I think it's wrong to have all the models one size. If a young person wants to be a model, they may try and become skinnier and become unhealthy, but if they let models be all sizes then it would let younger people become who they want to be. I also think its wrong to be small sizes because it has a bad influence on people."
Sarah, 11, Gloucestershire, England
"Models should not be forced to be super skinny. Anything from size 6-14 is fine."
Holly, 13, Newcastle, England
"I think that having normal size models on the catwalk is good because there is a lot of pressure on girls to be skinny. Also it shows normal size women and girls that you can still look good even if you're not size 0."
Laura, 13, Surrey, England
"I don't think it matters what size you are if you are a size 10, 12, or 14 because you aren't big if you are one of those sizes. But if you are bigger than that, then it does matter."
Hattie, 12, West Midlands, England
"I think that models shouldn't be super skinny because it might make younger children try and be skinny."
Ella, 12, Essex, England
"I think it doesn't matter what size a model is. It doesn't mean you are not pretty if you are fat. Too many people are trying to be skinny and I don't think it's healthy. Bigger models look more natural."
Amy, 10, Wales
"Just because a women has a bigger figure doesn't mean she can't look beautiful. Outside the catwalk bigger women wear the same clothes as skinnier ones, what's the big problem?"
Tasha, 12, Northamptonshire, England
"I think it doesn't matter what size a model is. It doesn't mean you are not pretty if you are fat. To many people are trying to be skinny and I don't think it's healthy. Bigger models look more natural."
Amy, 10, Wales
"I think it's wrong to put really skinny models on the catwalk because it's setting a bad example for kids."
Anna, 10, Lancashire, England
"I think a size 12-14 is more healthy than 8-10 because young girls will feel they need to be skinny and that 12-14 size is fat, which it's not. I think 12-14 is a good size to have on catwalks!!"
Lucy, 12, Oxford, England
"I think that the range of models should be a size 6-12. That way all different shapes and sizes are equal."
April, 13, Leicester, England
"I think curvy people are sooo much prettier than stick thin people. You don't have to be skinny to be beautiful."
Megan, 12, Leeds, England
"The size of models should not matter, if clothes are made for all sizes, they should be modelled in all sizes too, so we can see how they would fall on certain shapes or sizes."
Eleanor, 13, Hertfordshire, England
"It doesn't matter what size you are if you are a model so long as you make the clothes look good."
Willamina, 9, London, England
"No, it doesn't matter what size they are, all that should matter is how they are wearing the clothes and how they are modelling them!"
Lauren, 11, Wales
"It doesn't matter what size you are to be a model. I've watched loads of modelling shows and there are some plus size wannabe models. In one of the cycles a plus size girl did win. Don't worry about your size, don't let that get in the way of you becoming a model."
Natalie, 10, Nottingham, England
"I think it's good that bigger models are being used. I think models of all sizes should be used in the future."
Alice, 14, Worcester, England
"I think it does matter because you will get less sales if people promote them who are less attractive."
Jenna, 13, Manchester, England
"Everybody is different and people should accept these differences. People should not judge people the way people judge models."
Heather, 13, Yorkshire, England
"I think that it is really mean and silly to say that slightly bigger people can't look good in designer clothes. I would like to see more average sized people on the catwalk because it shows that it doesn't matter if you're not stick thin and really tall."
Jasmine, 13, UK
"It makes me feel kind of sick seeing really skinny models. I think models should be at least size 12 - this is an average size for a lady."
Suzanne, 14, Hertfordshire, England
"Loads of people say size doesn't matter. But when it comes to it, most models are thin, and people think people look better in the clothes they are modelling if they are thinner."
Harriet, 10, Essex, England
"I am so glad that one designer has sense to put bigger models on the catwalk. I don't think other designers realise how much pressure is on young people nowadays to be thin. I hope this is the start of good things and a change in the way the fashion weeks are constructed."
Lizzie, 13, England
"I think everyone, no matter what size they are, should get a chance at the catwalk. I mean, I'm a size 6, but I still think sizes above are cool!"
Fiza, 12, Manchester, England
"I think it's a great idea because if a model's too thin, it'll give everyone the impression that they have to be stick thin as well."
Iris, 12, Bristol, England
"It doesn't matter what size you are, as long as you look good in the clothes you are wearing. You are fine the way you are."
Chloe, 13, London, England
"It doesn't matter what shape you are as long as you are proud of who you are. They should let anyone be a model because they are just being mean."
Courtney, 10, Oldham, England
"I think it doesn't matter as no-one will notice."
Lucy, 11, Hertfordshire, England
"I think that it does because if they are too big then they will look awful."
Anisah, 10, Edinburgh, Scotland
