Best jeans ever!

Yes, I recommend this

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.

Great fit

Yes, I recommend this

Great fit, especially as available in an extra short leg length. I've now ordered another pair in a different colour. Very reasonable price.

Black extra short jeans

No, I don't recommend this

At 5ft 2 ins tall these jeans are fine with trainers, but too short with heels. I usually take a size 12 but these were far too tight, had to return and order a size 14. Never experienced that before! M&S sizing has always been spot on in the past.

Straight legged jeans never go out of fashion! Good quality denim, mid-rise, perfect fit, and reasonably priced. What's not to like?

Well done M&S! You have finally introduced (albeit a limited range!) 35" inside leg trousers...and these jeans are just perfect! A very happy customer! Please bring more of the same in different styles!

Great jeans, just hard to get hold of!

Yes, I recommend this

Have been buying these jeans for a few years now, in both black and dark blue. Love them. Fit well, wash well and at a great price. My only issue is that they’re often out of stock in stock in my size (12 reg) and although I managed to get a black pair, I am still waiting for the blue denim to come back into stock, it’s been well over a month!

Great all rounder

Yes, I recommend this

I have worn this style for about the last five years. A great everyday style, for work or leisure, dress up with a specia top or a nice colourful scarf. The Lycra makes them comfortable on journeys and they retain their shape for years of machine washing. Styles come and go( and I have those as well). but the Sienna endures for me. Great quality and variety of colours.
