Good quality. Great in longer length.

Originally posted on marksandspencer.com (UK)

Bought these school trousers for my tall and very slim 17 year old son. The age 13/14 fit perfectly with the longer length. Finding trousers has always been a problem as the correct age is always too wide for him. Wish I’d found this option sooner.

Bought the extra long leg for my 5ft 10 inch son, fit great & according to the tag there is an extra 3cm if I unpick the hem. Great adjustable waistband hopefully see him through the year.

Bought for tall slim child. Great fit. I am struggling to find trousers long enough but that aren’t too wide. These do the job nicely.

They fit well not too skinny and long enough for my 6ft 16 year old son. Adjustable waist is great as he is very slim.

Great trousers for my tall skinny son. Shame about how long it took for the size we needed for him to come back into stock.

A great fit around the hip for a slim person !

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I bought these trousers in skinny leg because I previously bought slim leg for years and something was not quite right in the fitting. My 14yr old son has a small pelvic area and a small waist . This time I was delighted with the fit and they were perfect because the skinny leg does his small frame justice! The material was flexible and soft, feeling comfortable. An added bonus is that my son will not wear a belt and the waist adjusters on the inside give security.

Waist too wide

Originally posted on marksandspencer.com (UK)

My son is regular height and size and these trousers had to be tightened on the waist so much that they look weird. The only reason I bought skinny fit was for the waist to match the fit but it did not work out. Last year’s slim fit ones were a similar story. They are otherwise good quality.

Great School Trousers

Originally posted on marksandspencer.com (UK)

The longer leg length is perfect for my slim tall 13 year old. We brought age 13-14. We had to adjust the waist but my son says the trousers are comfortable and there is room to grow with the let down hems when we need.

Bought for my daughter- great fit!

Originally posted on marksandspencer.com (UK)

Looking for my slender tall daughter the options for girls was limited. Perhaps worth adjusting to have a girls named version too. These are perfect they fit her in the leg exceptionally well. As with most trousers the elasticated waist is a game changer. This makes the fit just right as she’s very slender. Highly recommended.
