Long legg trousers.

Yes, I recommend this

The trousers fit very well. They were bought gor school uniform. They are for a 6ft 15yr old so although the waist is a bit bigger than his the adjustable waistband works wonderfully. I would recommend these trousers to anyone.

Great option for the taller child!

Yes, I recommend this

These are the only school trousers (at a sensible price) that I could find to fit my slim, 6ft tall 12 year old. He is happy to wear them although finds the (pricier) adult trousers more comfortable in terms of the fabric quality and overall fit.

Very slim son

Yes, I recommend this

Good quality. Good fit on my very slim son once the waist has been adjusted. It would be nice to be able to get a smaller waist in the Slim Leg, Longer Length trousers

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.

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!
