My favourite jeans ever

Yes, I recommend this

I consistently buy Siena style, as they are so flattering but comfortable at the same time. I have most colours and find they have at least a couple of years wear in them if well cared for. Highly recommended :)

The perfect jeans

These jeans are great because they sit nice on the waist. I like the straight leg as its not to tight on the legs. Very comfy and soft material

Good quality but does not fit.

Ordered my usual size 10 extra short jeans. M&S sizing is unpredictable these days and I will have to return these and order a size up. Hopefully they will fit better.

Overall a good buy

Yes, I recommend this

I live my life in jeans and often have trouble finding ones that fit well over my narrow hips. These are good quality, comfortable everyday jeans. They fit well over the hips and legs. I bought in 8 long and shall have to turn them up as from past experience a regular fit is not quite long enough.
