Great fitting jeans

Yes, I recommend this

I love these jeans. The cut fits me perfectly - I know I can pick a pair and buy them and they will fit perfectly when I get them home. I have them in several different colours/finishes.

I’m a big fan of the Sienna

Yes, I recommend this

Love the Sienna jeans, I have them in a range of colours. They’re comfortable and a bit stretchy which for me is a must. Hoping they continue to sell these as I like straight leg jeans, I’m not a fan of barrel or wide leg jeans.

Great Quality for price

Yes, I recommend this

Have bought several pairs of Sienna jeans in the past and very pleased with all. They are a perfect fit and true to size. Eventually after much wear and washing the elasticity does give way and they become a little baggy, but for the price they are very good value and last a good length of time.

The jeans are a flattering fit and inexpensive.

Yes, I recommend this

The black jeans were only £26 and a flattering fit. Have now bought another pair but in a different colour. They were easy to order online and were available for collection the next day.

I bought these straight leg jeans to replace exactly the same ones because I've lost weight. I really can't live without them.

Good comfortable fit

Great fit, very comfortable. Have not washed them yet so cannot comment on how they are after laundering. I have marked them down because I suspect the back of the studs contains something like nickel and they have irritated my skin. I have had to cover the back of the studs to prevent the irritation.

Size Up to avoid disappointment!!!!!

Yes, I recommend this

Having tried on 10 pairs of M&S jeans recently without any luck due to sizing issues I finally found these. I'm very pleased with them, lovely black denim, great length and shape and a very good price. However there is still a sizing issue. All my old M&S jeans are size 12 but the only way I could find jeans to fit this time was by sizing up to a size 14 and wear with a Belt. Good job I don't have an eating disorder as this is not good for your self esteem!!! I now submit and accept that the new M&S size 12 is in fact a size 14!!! I'm a petite 5ft and I purchased the Extra Short which are the perfect ankle length on me. I really recommend these beautiful jeans but do size up.
