These are for my son. Unfortunately they are not very long in the leg for the age they have been bought for. My son is not tall but they are likely to only last a month. Delivered quickly though.

I have been buying these jeans for a number of years for my grandsons, they are very good at putting clothing to the test for durability. These jeans wash and wear very well, and have the advantage of an adjustable waist. My grandsons are tall, so long legs but quite slim, these jeans really fit well, usually buy a size or two larger than their ages to get the length.

Excellent fit and comfort. Bought as I've lost height and have been unable to find an adult pair that fit me in both waist and height.

Sizing is wrong

Originally posted on marksandspencer.com (UK)

I purchased a dark denim pair in size 13/14. They fitted well but my grandson didnt like the colour, so i purchased a 13/14 slim fit in thee pale blue but they are smaller than the dark denim and dont fit, if you measure the two pairs both the size size the pale ones are much smaller.

Well cut, good fit with adjustable waist. M&S children's jeans are always sound quality, reliable and competitively priced. I have purchased M&S jeans for my children baby to teen. Always happy. Wash and wear well.

Highly recommended boys jeans

Originally posted on marksandspencer.com (UK)

Excellent indigo colour and long length bought for my tall, slim grandson. He is quite fussy and I was pleased when he wore them straight away. Much better quality than high street competitors.

I bought these for my grandson because it said slim jeans. Label on them says relaxed fit. Are they slim or relaxed? Putting them in with his Christmas gifts. He is 12 but had to buy 15/16 as he is tall and slim. Wish M&S would do some research on heights etc . A lot of 12 year olds are very tall and slim so it would be good to find clothes to suit.

Had to exchange them for a different colour as the one received wasn't as expected.

Bought these for my son as he just loves the quality of the jeans. We have dogs and cats at home and the good thing is that pet hairs DON'T stick to the trousers, which is great!
