Nice quality jeans

Yes, I recommend this

The quality and fit of the jeans is good. However, when taken from the package they were so creased I had to steam iron them twice and they’re still creased! So, packaging not good!

Comfortable stretchy jeans

Yes, I recommend this

Fit perfectly and great to have longer length as regular size a bit too short for me. Bought another pair in a different colour as they were so comfortable. The straight leg design were like a slim version which suited me much better than their actual slim designed jeans.

Bought petite size but disappointed by the length

No, I don't recommend this

Bought petite size but was disappointingly long. Not the same length as the last pair of petite straight leg jeans I have bought from M&S. Will need to take up anyway. In every other way good fit and prompt delivery etc.

Extra long leg

Yes, I recommend this

The fit was fairly true to size but they were shorter in the leg than expected - actual inside leg length is 33". Just long enough for me with flat shoes but be aware.

Change in cut? Not quite the same as previous

Has the cut of Sienna changed? Seem baggier and the cloth is stiffer.

Not consistent in sizes

No, I don't recommend this

Bought a size 18 in shop and they were slightly tight so ordered online a size 20 and they were too large. There seems to be a problem with you clothes as the sizing is always different. Maybe you should get your products from one manufacturer instead of several!

Lovely high waisted jeans.

I was very pleased to find that the size 10, regular length jeans fitted me - I haven’t been a size 10 for many years. (I do realise that clothe sizes are much more generous these days). I always needed the longer length in trousers, but for some time the new longer regular has been fine.

Good quality jeans

Yes, I recommend this

I'm happy with my jeans but prefer the Cigarette style I've had before which are a more flattering fit. I couldn't find Cigarette jeans online. I ordered short and had to have them shortened by 3 inches, I'm 5'1"
