Too short

Bought because I couldn't get short leg. And although the leg length was ok. The body length was too short.

Quality as good as always

Yes, I recommend this

Bought similar M&S jeans years ago and still wearing them. Purchased these to add to my others as they last forever, wash well and the quality is excellent. What’s not to love with them, have some stretch and a choice of lengths.

Not the same

No, I don't recommend this

Had another pair and they fitted perfectly. They’ve changed the style so these are now mid rise and the sizing is all off.

Happy with my purchase.

Very happy with these jeans. The dark indigo is very dark almost black which I love as I think they will look good when the summer comes. I am five foot nothing and the Extra Short length is perfect so I'm thrilled with that. I ordered a size 12 which is true to size and they are as it says on the tin, they are straight leg. Other straight leg jeans I've order from other companies on line have been actually wide.

Bad fit

No, I don't recommend this

I have several pairs of sienna straight jeans size 14 and am still wearing them, but the jeans I ordered were too tight, m & s sizing is completely unpredictable at present.

Sienna straight

With so many different leg shapes to choose from I still prefer the sienna straight, I am a retired lady so still prefer old style, I do find them a little wide at the top of the leg, but very comfortable to wear, great price to.
