Great fit, style & quality

Yes, I recommend this

Great fit & style. I am usually a regular leg, but M&S jeans & trousers reg leg are longer so bear this in mind if considering.

Smart jeans

Yes, I recommend this

These are my favourite style and finding a pair in dark denim that fit well in my size has not been easy. This pair was a lucky find and, although they are a snugger titan my old ones, the length is better and the colour is great.

Size issue

No, I don't recommend this

Ordered same size as bought 2 days earlier in store but in a different colour. These arrived and were considerably smaller size in waist. Had to be returned to store.

Great everyday jeans

Yes, I recommend this

Good everyday jeans that are easy to wear. I have now bought 2 different colors and they form a casual wardrobe staple. Size in M&S jeans tends to be a little more generous than other makes but can get great belts as well.

Came up large, not very flattering

No, I don't recommend this

Looks great on the model but made me feel all of my 56 years, lumpy and frumpy! I bought a 12, my usual size, and probably could have gone down to a 10. No idea what shoes to wear with them. I have the flats that the model is wearing, but just made the whole outfit feel dowdy. Price pushed my rating up to 3 stars

This is the second pair I have bought , the first pair about 3 years ago and I’m pleased to say that the fit and quality are the same as the originals. Amazing ! One can never be sure if the new ones are going to match up !

Soft and flexible.

Yes, I recommend this

Great fabric, with stretch. Wanted to like them but the 12 were too baggy and the 10 way too tight so not the right style for me. Or I am size 11!

Greta slim fit jeans

These are great quality jeans if you want a slim fit. They fit well without being high rise.I've been buying them for years but they are not really straight leg. I would say they were slim fit as they are quite narrow at the hem. If you want a straight leg try M&S Roma straight leg jeans which really are straight leg.

Sierra straight leg jeans.

No, I don't recommend this

Good fit but very tight to get over the feet while putting them on . Could be impossible for anyone with large feet!

Love the colour

Yes, I recommend this

Perfect for those of us who live in black denim and fancy a blue option. Stretch makes these very comfy for my curvy body. I’m a 10/12 and went for the 10 so they stayed slick on my shape… love wearing these!
