Almost perfect for me.

Yes, I recommend this

Would like a higher waist, otherwise perfect fit for me. Lenght great (short) as I am 5ft 4". Quality very good, feels nice and comfortable on. Price also very good, well worth the money. I will be buying other colours. How about some pretty pastels for summer? On the whole - one satisfied customer.

Perfect fit I am a size 14 5’3” and orders the 14 short. They fit perfectly. They are also so comfortable to wear. Not washed them but the denim had a lovely feel to it.

Happy

Yes, I recommend this

It was very hard to get my size in these. I'm 5ft2 size 12. I ended up getting 12 extra short as I couldn't get the short. It finishes at my ankle which is nice for the summer. I got to replace an old pair that I had for 2 years and wore to death. They seem to be the same quality as 2 years ago. Sizing is still true to size for me, tho m&s sizing is more generous than other highstreet brands. The - 1 star is because, although well worth £25 I'd pay more for them to be better quality and last longer than 2yrs.

The fit is not consistent.

Yes, I recommend this

First of all I bought 3 pairs of the high waisted jeans - short, but not short enough. By the time I got round to shortening them, it was too late to return them, which I should have done because for some reason the rise is far too long for a short person. Why make it the same as for a tall person? As a result they are not very comfortable to wear. Then I had a lightbulb moment and bought Sienna mid rise in Extra Short which is actually the right rise for a short person and also the right length. Much as I used to prefer high waisted I won’t be buying anymore! They are a poor choice for a short person. The inconsistency arises when trying on several pairs. They all fit differently. I bought 3 pairs of the mid rise and two pairs are going back. For example, one leg of the black pair bunched up around the knee.

Always great to have dark blue denim to wear. Lots of stretch. Hope they wash well. Length is fine for me, being 5’3” - I prefer a turn-up, so regular fit well.

These jeans are my "go to" purchase. The sizing is consistent over time. They wear well, wash well and are very comfortable as everyday wear.
