Right length for slim & tall 10 year old.

Yes, I recommend this

Great to finally have a pair that fits length wise and isn’t too bulky around the waist. Child says they can still run and move in them (reason they don’t usually like trousers) and having warm ankles helps. Good quality.

Just the extra length needed for a very tall boy

Yes, I recommend this

As the mother of a very tall but very slim teenaged son, these trousers are a lifesaver. The extra 8 cm length are absolutely perfect, and the slim fit looks more professional for school than the super skinny trousers we tried that fit but just didn't quite look right as a school headline.

Great quality

No, I don't recommend this

These trousers are great quality and also have an adjustable waistband which is very helpful for a very tall slim 14-year-old.

Perfect for slim and tall children.

Yes, I recommend this

I am so grateful for the extra long option. My child has been wearing trousers that are too big on the waist in order to get the length. These trousers are perfect!

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!

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
