Highly recommend

Yes, I recommend this

Fabulous for boys who are tall and slim. My 11 year old has been wearing 12-13 Extra long and it’s great to know he’ll actually get some wear out of these before growing taller. Have bought 6 pairs, highly recommend

Well made, perfect fit for a slim growing teenager

Yes, I recommend this

Our son is a slim 15 year old with 30/31 inch waist but rapidly growing legs (31/32" inside leg). We purchased these just before start of term and were lucky to find stock but they fit really well - bottom of the trousers cover the top of the shoes (without exposing the socks!), legs are not skinny but also not too loose (he finds this convenient for changing for PE classes). It is great to see that M&S do these longer leg trousers - so helpful for rapidly growing slim teenagers...and well made with good quality fabric

Clasp on waistband

No, I don't recommend this

These are good trousers and I always buy them but after a few wears the clasp on the waistband becomes weakened and widened and the trousers no longer do up, a button would be better, any suggestions on how to fix this I would welcome please

Tall and skinny children… these are what you need!

Yes, I recommend this

My 8 year old son has a tiny waist (5-6 realistically) but incredibly tall, almost 140cm so these trousers with the extra length; grow proof hems and the adjustable button waist are absolutely what the Dr ordered. The crease lines in these trousers last all school year, I hate ironing so a wash and hang straight up out the washer and they are almost perfect every time. He plays football after school in them almost each night and they last and remain smart from September to April/May when he starts wearing shorts. I cannot fault them in anyway. Worth every penny and more.

Extra length is great

Yes, I recommend this

We use these extra length trousers for our tall, slim son by going one age group lower to get the right waste size, and getting the extra long version. They fit him perfectly.

Perfect fit

Yes, I recommend this

Perfect fit finally! My 13yr old is tall, with big feet, so has outgrown the length of 15yrs trousers, but doesn’t have the waist or hips of a 16yr old and skinny fit look stupid. These were perfect!

Solution for tall slim children

Yes, I recommend this

I always buy these for my son as it’s very difficult to get clothes for tall slim children. Recently, changes have been made to these. The material is different and, although I bought the same size (12-13, slim fit, long) the leg width is wider and the length is about 1.5 inches longer. Tumble drying them has helped and they are acceptable, but it’s very annoying when retailers just change the measurements - what is the reason for this? The change of material is an improvement though, it’s thicker and softer. Hopefully my son won’t go through the knees in these (as he often did with the old material).

Best school trousers

Yes, I recommend this

Love these school trousers, small enough waist and plenty long enough leg to get through most of the school year. We always struggle getting long enough legs with a small waist and these fit the bill perfectly. They wash great despite the paint, pen marks and grass stains. Never had any holes in the knees and don't ever look worn in the knees despite all the football celebrations at lunch time!
