Hard Wearing

I buy these (5 pairs) every year for work. I work in Early Years so they need to be tough. Also they are reasonably priced.

Great everyday - easy breezy jeans

Yes, I recommend this

I find these jeans, a great fit; perhaps slightly on the smaller side. I am a size 10 and they fit well, I did also order the same jeans in the darker wash, and they came up slightly tighter.

Inconsistency

No, I don't recommend this

I have bought the same jeans several times over several years but recently the sizing has varied too much. The short jeans are now longer and tighter on the legs. I know fashions change but don’t sell them under the same name! The quality and price remain good though

M&S you need to sort out your sizing!!

Yes, I recommend this

Comfortable jeans. These are my third pair. However, I had to go back and forth to the store to get the right size. I’ve been an 18 regular for years. This time, I’ve ended up with a size 20 short!

Sad that Extra Long length is being discontinued

Yes, I recommend this

I absolutely love these jeans, and have bought all the pairs I can in as many colours as I can, because I know that they are being phased out in the Extra Long fitting. There are such limited options for really tall women when it comes to jeans, and these from M&S (together with the Lily style) are total winners. It makes me very sad that M&S have decided to stop offering them, and I hope that the decision might yet be reversed.

Different sizes.

Yes, I recommend this

I have worn Sienna jeans for some time. I ordered 2 more pairs recently - both Size 14 short, but different colours. One pair is much longer than the other. Why can’t sizing be more consistent?

Great Quality fitting Jeans.

Great jeans, true to fit. I struggled to get extra short but these fit perfect. Good value, just missed the 20% off.

One of best blue jeans I've had

Yes, I recommend this

Comfortable fit, really soft and flexible but good quality. Wash well, iron with ease. I'm 5' 5" tall and purchased short length which comes to just below ankle bone. Liked so much that I tried to get similar in black but unfortunately these felt stiff and not as good fit.
