Well made and styled jeans - love the dark indigo colour. Comfortable as they are stretchy.

Poor quality anf very thin material

No, I don't recommend this

I have ordered these jeans before and was quite pleased with them. This time around however, they were much poorer quality and very thin, maybe M&S have changed supplier. I have since returned them.

A lovely product

Yes, I recommend this

I really like my new jeans. Initially I worried that they might be too tight, but they stretch beautifully and adapt to one's shape.

Just the job

Yes, I recommend this

I normally wear slim jeans but after knee surgery I couldn’t. I was hoping that the straight jeans wouldn’t be too baggy but they are perfect.

Sienna black jeans

No, I don't recommend this

Ordered black jeans , in same size as blue jeans previously purchased. They are dreadful. Do not fit in the same way. Leg width too baggy. How can both pairs of jeans called sienna be so different? Not recommended at all

Good but inconsistent sizing

These jeans are great if you can manage to get the right size but every colour has a different sizing and from one season to the next even that changes. Currently wearing a size 16 in the indigo and squeezing into a size 18 in the black. Now my local store dosent stock longer lengths, I have to order 4 sizes to buy one pair.

Bit loose

No, I don't recommend this

I'm sure I've bought this before in the same size but these are a bit baggy round the thighs. Great for country walks,where I don't mind if they get muddy!
