Nice quality, fit well, easy to wear.

Yes, I recommend this

I have been buying these jeans for years now. I like the fit on me, I have them in grey, white and a lighter denim. It would be nice to see them in other colours. They are a nice quality and easy to wear.

Delighted but confused

Yes, I recommend this

I wanted some straight dark blue trousers, but all in store had yellow stitching down the outside leg seam. The assistant and I decided the only thing I could do was to order the correct size (18 L) and cover the yellow stitching with a dark pen, imagine my delight when the trousers arrived and there was no yellow stitching, just an inside seam!!

These jeans fit so well, soft feel & really comfy. I ordered the short/petite & needn’t have worried as they’re the perfect length & I’m 5’3”. Will be ordering more in black. Would definitely recommend them.

Regular length perfect for 5’6”’ Height.

Yes, I recommend this

Indigo mix jeans, no waist gapping and even colour dye so can be dressed up with a jacket or down for casual look.

Comfortable Jeans

Very happy with the jeans, but as my local store didn’t have them in my size I ordered on line. I then discovered that I was charged a delivery fee and couldn’t use click and collect. This negated the discount offered on jeans/ trousers . The lovely lady at customer services took off the delivery charge…but please be aware if you order on line

Good every day jeans

Yes, I recommend this

Great jeans for every day wear, medium thickness and with stretch for comfort, however did have to buy a size larger than my normal size as they seem to be small compared to the same jeans in a lighter colour

Third pair

Yes, I recommend this

I have these jeans in 3 colours now. White, light blue and the latest being the indigo, all size 10 and regular length. This pair however seem smaller but with the elasticity still manage to fit, albeit a bit tighter. The length is much longer too and I’ve had to take them up to fit better. Still decent jeans.

Best straight jeans!

Yes, I recommend this

The one thing M&S do well are their quality jeans especially for the petite woman! Perfect fit & perfect length. I’m 5’3 & the short fit was perfect! Good quality heft of denim too.
