3rd pair I have brought!!

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

Originally posted on marksandspencer.com (UK)

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

Originally posted on marksandspencer.com (UK)

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.

Originally posted on marksandspencer.com (UK)

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.

Originally posted on marksandspencer.com (UK)

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.

These jeans are very comfortable and a very good fit, it’s a shame that I can’t find the longer length in the shops and had to order online

Why change a good thing?

No, I don't recommend this

I’ve been buying Sienna dark indigo jeans for years. Always been lovely plain jeans. So what have M&S done? Used orange stitching instead of the usual dark colour which blendedin with the material. Sigh.

Sizing is so random leg length vary, find that the lily and sienna not consistent in the sizing. So I thought I could buy on line like for like as previous jeans in this style and size had been fine. But unfortunately not I should have returned them

Love these jeans, so comfy and they seem to suit my body shape (tall and skinny) I usually struggle to get a comfortable fit at waist and hips.
