Look really smart

Yes, I recommend this

I love the look of these trousers, they are smart and a good weight of fabric. However, I don’t use a tumble dryer and these are really hard to iron once they are dry

M&S recognises kids come in different sizes!!

Yes, I recommend this

Perfect for my son who is taller than average but also very slim. M&S is the only place who recognises that kids have different heights and builds. Adjustable waist and long length. Have bought these for years and will continue to do so whilst he is at school. Thank you!

Great lengths

Yes, I recommend this

Just what we needed for my slim boy with longer legs. The Next trousers we bought looked like ankle bangers unfortunately, they didnt have longer leg in stock. M&S came to the rescue.

Unavailable for weeks

This item has not been in stock to order since before the summer holidays been on wish list for ages. Grey, longer length slim aged 16-17 school trousers. Very disappointed as too expensive and difficult to find elsewhere!

Slim kids need

Yes, I recommend this

If your kid is tall but a picky eater that’s a good product. They should create more designs for jeans and joggers for a daily life too

Great school trousers.

Great trousers. They are good value and fit my son length wise as he is very tall. We had to go for the 17-18 as he is 6 ft 3. Sadly he is only 13 so if he grows any more there are no more school trousers available - please do some longer leg lengths for children that are very tall.

Perfect for tall kids

Yes, I recommend this

By far the best fitting school trousers I have found for my very tall and slim boys. The extra long length is brilliant so we don't have to choose between a hugely bunched up waist or ankle swingers!

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.
