Bought for son to go to Sixth Form with matching jacket. Nice slim fit. Material is ok, it’s quite thin for the price. I’ve had better quality at other stores for a similar price. Wash well and barely need ironing.

The fit is excellent and the material used is good quality. The only criticism is that the side pockets are very shallow, keys and loose change fall out when you sit down on a chair.

No, I don't recommend this

Poor quality with very thin fabric. The children’s school trousers match with the suit jacket and are much better quality and cheaper.

Decent stylish trousers

Originally posted on marksandspencer.com (UK)

Purchased with jacket. Bought a 34 regular and was slightly hesitant at them being a good fit as they are slim fit however they fit nicely. I am 5 ft 8 in and weigh 11st 8lb. Machine wash which is a plus. Nice feel and do not crush- tried and tested as I wore the suit for a whole day.

An emergency buy online for an unplanned occasion. Great fit, classic style and a brilliant price. Looked much more expensive than it was matched with a good shirt and a good pair of shoes.

good sale and fit

Originally posted on marksandspencer.com (UK)

for the price excellent value, good sizing & fit, even jack comes in short so sleeves are the right size. Material is a bit thin but again at this price point noting to complain about. The only thing was there was none of these cheaper suits instore, had to order it on-line. It came the next day which was fine but if you are trying to get people in your stores then stock your cheaper products too.

Nice fit, easy to wash and iron, and the longer length option works well for my son who grows taller by the day.
