Lovely and long!

Purchased as my son keeps growing (why do kids do that?) - the longer length plus the extra hem you can let down means sometimes his trousers nearly last a while school year before he grows out of them!!

Great boys trousers, had to purchase as my son is 13 and is nearly 6ft! He grows out of trousers so quickly but these are perfect in length and should last a while. They wash up well and last well. Can pull in at the waist as well which is a bonus.

Great school trousers

M&S school wear is always the best. Trousers are good quality, true to size and last very long. These also look very smart so can be sometimes disguised as a formal wear for teenagers.

Not great for slim teenagers, but better than most

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Always bought these in the slim leg/slim waist fit that was perfect for son, but they were getting too short even with the hem let out. Turns out the inseam is 31” for all sizes above 15 years, so the difference between 15-16 and 16-17 and above is just an ever expanding waist size. Why? A typical adult inseam is 32”, and my 15-year-old has reached that and will probably need longer. So these ones are now regular waist/slim leg a size down, with the long leg. The leg fit is good from the knee down, but we needed to cinch in the waist to the max, so looking a little ridiculous at the top. These are such nice trousers otherwise and good quality, but that is so disappointing. Why is everyone just catering for the “sturdier” teenagers, not the slim ones? You can do better, M&S.

Perfect fit for a slim tall 14 year old. No longer have to go up a size and get ones that are too baggy or big around the waist.

Quality Trousers - even longer length please!

Originally posted on marksandspencer.com (UK)

Quality trousers, a nice slim fit for the slimmer boy. I had expected these to be the full 33 3/4 inch length as per the listing, but they were 32 1/2 inches & I had to let them down to achieve 33 3/4, just sufficient for my very tall slim 13 year old. I already sized up to get the max length, his waist is typical of a 12/13 year old. My son is still growing and I usually buy him a 28w 34l online as they're so hard to find, please M&S can you make these trousers the full 33 3/4 length plus growing room. They're the longest school trousers on the market but we need still longer please!

Good fit for tall slim teenager.

Originally posted on marksandspencer.com (UK)

Good fit for tall slim teenager. Material is thinner than previous years so don’t see them lasting so well. Shame because M&S are about the only place to get school trousers for older teens without paying the price for adult trousers. Also had to wait for charcoal to come back in stock.

Good length

Originally posted on marksandspencer.com (UK)

These trousers are good,they still have the adjustable waist. My son is 14 but nearly 6ft and these are a good length. They are more expensive than I would like but I was desperate after my son’s growth spurt. It’s a shame longer length aren’t more available and when they are they’re often out of stock.

My son is only 14 but 6’1 and getting school trousers is not easy. These are great but I am disappointed that there are not in a two pack and the older ages are always sold out online!

Great quality product for the price and arrived quickly. The best thing has been the options for waist and long / extra long which my son needs. It’s refreshing when companies make clothes where a larger size doesn’t just mean “fatter”.

Great for tall but slim boys

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

My son is sporty, quite tall for his age, but very slim around the waist so often trousers thatvare the right length are far too big round the waist. These are perfect. I can buy a smaller size to fit the waist but a longer length so they're not too short. Nice material and wash well too.
