Too wide

No, I don't recommend this

I got these for my son age 17. He's very tall and thin. These are the right leg length but far too wide. I wish I could find skinny fit trousers that are still long in the leg.

Great length, keep in stock please!

Yes, I recommend this

Great trousers, good quality and the longer length is really helpful for tall boys with a slim waist, just wish they were in stock more often.

Ok, but…

No, I don't recommend this

Great school trousers, but the clasp to fasten them fails after a short while. It becomes loose and then it is unable to secure the trousers properly. This had happened on the previous school trousers too. I bought these in September and already the clasp has failed, it’s only October!

Great quality and amazing fit!

Yes, I recommend this

Good fit for my son’s long legs. I like the stretch material as well as it makes the trousers comfy as well. The price is good value for how well it wears.

Brilliant school trousers

Yes, I recommend this

These are ideal for my 15yr old grandson. He is very tall and slim which makes it a nightmare to buy trousers for! I buy 16/17 for him but because they have an adjustable waist he can wear them without a belt which aren’t allowed in his school, the extra length means they should last until the end of the school year

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 2 pairs when the 2pack was out of stock, highly recommend
