Tall and skinny ✅

Yes, I recommend this

Age 14-15 extra long is the longest slimmest combination of these boys' school trousers. Just hoping my skinny 15 year old doesn't grow much taller! Adjustable waist and unpickable hems = useful features.

The only ones long enough

Yes, I recommend this

Very good quality school trousers, doubt if they would ever wear out. Most of all, these are the only ones we can find with a decent length and they appear slightly longer than last years, which is a relief as our boy’s legs are longer too, with the bonus droppable hem in reserve.

Lovely and long!

Yes, I recommend this

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 quality, great fit

Yes, I recommend this

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

Yes, I recommend this

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

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!

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.

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.
