Mainly buy bootleg but for a trip to Nashville thought these more appropriate. Lovely soft denim, perfect leg length and extremely comfortable. Perfect sizing and a great price.

Excellent basic jeans. As they are stretchy they are a great fit without feeling stiff.

Sizing not quite right for my shape

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Rather baggy, but comfortable. I’m in between two sizes. Size 14 too tight and Size 16 too baggy. I really wanted them to fit as they are lovely jeans.

Quality fit and style great!

Originally posted on marksandspencer.com (UK)

The quality and fit of these jeans are great I bought a long 12 and they fir really well with a bit of strech and they are mid weight denim, not too heavy for transitional season. The only thing I didn't like was the sticky label on the leg left a line of glue so you can see where it's peeled off. Hopefully will come out in the wash!

Have worn sienna straight for many years.

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Very disappointed with the shape and cut of these black mix jeans. They are wider than usual and cut more like men’s jeans. The top of one leg twists and doesn’t fit the thigh well. I only want them for dog walking so have not returned them. Would not recommend them for best wear. Very disappointed.

Best jeans ever!

Originally posted on marksandspencer.com (UK)

For me, these are the perfect jean. Straight leg, just the right amount of stretch without being baggy but so comfortable. Ideal for everyday life but still smart enough to wear with a nice top too.
