I always buy these jeans as they are such good value for money. However my latest pair is slightly smaller than usual. I shall have to lose a few pounds!

So comfortable and a good fit. Delighted with long and extra long options. Good colour options but I avoid the ones with orange stitching.

Good fit

Yes, I recommend this

It’s stretchy and suitable for more curvy figures. I’ve given 4 stars because it does tend to pick up a lot of lint. Otherwise it fits well and is very comfortable

Good fit.

At last, jeans that fit. It’s so difficult to find jeans that aren’t high rise, these Sienna straight leg jeans are excellent. I have ordered further colours.

Poorer quality than previous iterations

No, I don't recommend this

Bought in black. Good fit, but disappointingly the new fabric seems to be lint-attracting. Previous fabric used was much more durable for everyday use.

Size problems with these Jeans

I have several pairs of these Jeans in various colours, all the same size. They all fit perfectly except the new ones which come up a size smaller. Tried the next size up and they are too big. Definitely need some quality control M&S and consistency in sizing!

Quality not as good as it used to be

Yes, I recommend this

Please M&S i ordered short which is usually ok but I've had to take 2 inches off! This so often happens! I always buy M&S jeans as the fit is okfor me but you've let me down this time. Quality acceptable but not as good as it used to be.
