Dog walking jeans

Yes, I recommend this

These are good value basics for everyday chores/dog walking etc. Fabric a bit soft for my likiing and the design and style has definitely changed, not for the better, in recent years. For example, my older ones are better quality fabric and have smaller rear pockets. Sienna used to be my go to for everything but now relegated to casual housework jeans which is a shame. Still fit well and long enough in size10L, just somehow downgraded and look cheaper. Not what they were a few years ago....

Extra short leg length unavailable, if I keep the short ones I received I will need to pay £12 to get them shortened. This has only happened since the new leg lengths were introduced - annoying

Very happy to find my size in these straight leg jeans in store. They are a smart, casual look which I found to be very well made and true to size. Very happy and wish I could find more of them in store or online.

My favourite jeans

Yes, I recommend this

I have been wearing Sienna Straight Leg Jeans for many years. They have a slight stretch which makes them so comfortable to wear and as I know my size and length re ordering is so easy. They come in several colours and they look and feel so smart on.

Very Good Value

They are extremely good value. I would have liked them to be a little less loose in the leg, but overall very happy with them.

Good fit

Yes, I recommend this

Nice fit. I prefer the higher waistband & straight legs to skinny. The stretch in them makes them comfy. Wish M&S sold extra short leg length in shops (in Cornwall at least) & didn’t run out of stock on them as often as they do.

Great fitting jeans

Yes, I recommend this

Great jeans. Fit well on the waist and on the hips. This is the first time I’ve been able to get M&S jeans that are long enough. I’m very long in the leg and arms and I bought the extra long and they are perfect! Unfortunately unless M&S do a longer length sleeve. I’ve never been able to buy a coat or jacket.
