ShoppingNan123 Sienna Straight Leg Jeans with Stretch Slight baggy from the knee down. but good value and I would buy again

19helen53 Too wide Lovely fit on the waist and bottom but far too wide in the leg. Could you produce some straight narrow leg jeans please.

Dezyanez Great Waist a little big but comfortable and washes well.

TobyTwizzle Great pair of jeans These are the third pair of sienna jeans that I have bought. They are a good fit and comfortable. They also wash well too.

Liz B 1961 Lily and Sienna Jeans - excellent fit and comfort excellent purchases - stretch gives comfortable fit. Have now purchased the an additional 3 pairs of Sienna jeans. Great value for money and will be purchasing more.

JoJasper Way too much stretch!! I have been buying these jeans for quite a few years and have always found them to be a great fit and very comfortable but having just brought another pair I was really disappointed to find M&S have changed the material and added far too much stretch so they now bag up around the knee and don't hang nicely as they used too. Please M&S go back to the original material which was way better!!

Lizzie Royston Good fit Nice shaped leg , not too tapered. A good fit all round

Les123456789 Not good. Bought 2 pairs, they felt really comfortable. Unfortunately after wearing for a few hours they go baggy round the waist and I'm constantly pulling them up. Tighter on thighs than the old style, also not comfortable after a few hours, but it does stop them falling off completely! Definitely not boot cut, way too narrow. I wouldnt recommend these and I'd send mine back if I hadn't worn them.

Elaine644 Length??? I thought I’d ordered regular length (I was always regular) but short was delivered. A good job because short length was petfect.

Ail13 Fit of Sienna jeans Comfortable to wear but find them too large over bottom for slim hipped people. I buy the smaller size to what I usually wear. Beware of colour transference on sofa!!

GNE Good fit. Too long will be returned. However they are a very good fit..

styleshopper47 comfy fit Yes these jeans feel comfortable but are too long for me 5 ft but if you turn up the bottoms like I have, still look good until you wash them and then can alter them to the length you want them in case they have shrunk?

handbagfanatic Great fit and style Great fit and really comfortable. I bought the short and they are okay but longer than previously bought short length trousers and jeans. I bought the very dark blue and they are lovely.

WriterAtHome Good quality black jeans These black jeans are comfortable on, the material is nice and soft, and they’re a good fit and perfect length.

Moragbellingham Value for money Very pleased with these jeans - good value for money - comfy & roomy

null Jeans for any age These jeans are very comfortable to wear and fit really well

goingplaces Short legged lady At last a perfect fit, not easy when you have short legs

Isiot Well made & comfortable trousers This is my 2nd pair because they fit well are warm & comfortable. True you need to shorten them but well worth the effort.

JR130 Jeans that fit!! This is the second pair that ive recently purchased

Ifyouwantthis review Good fit These are a good fit and the material is comfy and a reasonable price
