Good fit.

Yes, I recommend this

Very good value for money jeans, they come up a bit long in the leg, so I bought a shorter pair than I usually do.

Disappointed

No, I don't recommend this

The Sienna range was always a perfect fit until M&S made"improvements", now the legs are too tight and the larger size hang on me. I now gi elsewhere.

3rd pair I have brought!!

Yes, I recommend this

3rd pair of these jeans I brought, fantastic everyday pair – really flattering with a classic cut that suits everything. The fit is true to size and the stretch denim makes them super comfortable to wear all day. They have a nice, neat shape that feels both modern and timeless, and they’re easy to dress up or down. Great quality for the price definitely a reliable wardrobe staple.

Sienna mid rise jeans

Yes, I recommend this

I waited for ages to get the dark blue jeans as I already have the paler blue Sienna. As I am over 65 I think darker blue is more flattering. However, the new darker jeans are mid rise, not up to the waist like the pale ones. A little disappointed that I missed that detail.

Great value for money, but could be a bit longer

Yes, I recommend this

I ordered these jeans as have a couple of pairs of skinny jeans but wanted a straight leg pair. Excellent value for money, really good quality, but as a taller lady, I ordered long and they come to my ankle bone- could do with an extra inch on the length, but otherwise would have got 5 stars

Good value jeans.

Good colour and comfortable jeans. At last I managed to get an extra short pair so at 5 ft 2 the length was just right. I used to buy size 10 short which were perfect until the sizing changed-don’t know why!

Thin jeans- best for warm days.

These looked nice but the fabric is not as soft as I expected it to be. The cut’s ok but I have had better more comfortable jeans elsewhere.
