Sienna jeans

Yes, I recommend this

I bought a pair of both black & denim Sienna jeans as I have had them both before. They’re versatile for both every day & smart casual wear, fit perfectly & wash well. Great value for money. They are both size 12, short leg but the black are longer in the leg than the denim blue.

So pleased to find jeans long enough for me - 35” leg length. Would have preferred less stretch but nice quality. I hope more styles will also have extra long in future

Variable sizing.

No, I don't recommend this

I have one pair of these which fit well , not an easy thing to find at my age and height so I ordered 2 more pairs in white and black . White jeans fitted but black jeans too tight and too long so had to be returned. For years I could rely on m&s short fitting jeans , now it’s a lottery,very frustrating.

Great Fit

Yes, I recommend this

These jeans fit perfectly. I love the colour, its called dark indigo but they are more of a mid blue. The material seems hardwearing and they are well made. The regular is just the right length for me. I'm 5'7".

I have bought these before. As a tall, slim woman, (5' 9'" and size 8) I know they fit well, and they hold their colour for quite a long time.

The perfect jeans.

Yes, I recommend this

I couldn't be more pleased with these jeans. I gambled and bought them online because other 'Sienna' partnership clothes I've bought from M&S have been very stylish and great quality. These are so nicely cut -slim and straight, but not tight- really comfortable at the waist and flattering. I've recently decided to throw out some old jeans so I have bought these in all the colourways as they are also great value. I will be wearing them every day.

Good quality, shame about the length.

Yes, I recommend this

I bought size 14 short as the extra short length was out of stock or never existed. I am 5ft 1ins tall and experience has taught me that the short length is over 6ins too long. Apart from cutting a lot off the length the jeans seem to be good quality and sizing is consistent, unlike Per Una.
