Every woman's wardrobe needs a pair of go-to trousers that they can just throw on without thinking, and we're convinced we've found the ultimate pair.
As versatile as they come, you can dress them up with a blazer and blouse for work, or dress them down with a jumper and trainers for running errands.
With over 8,000 reviews and counting, there's a reason they often appear at the top of the retailer's list of bestsellers.
Why we rate it
The straight leg silhouette gives them a loose and flattering fit, while the elasticated waistband ensures all day comfort. They're made using sustainable cotton with added stretch for optimum comfort and added warmth (a bonus during the colder months).
If that wasn’t enough, they feature M&S’s StayNEW technology to prevent fading and bobbling (the curse of many a stretchy trouser), meaning they'll last you forever.
The trousers are available in sizes 6 to 24 and in seven (count 'em!) colours: charcoal, navy, black, chocolate, dark burgundy, indigo and pine green.
You can also get them in a range of leg lengths from extra short to extra long.
What the reviews say
Don’t just take our word for it though, the trousers boast over 4,900 five-star reviews. In fact, one shopper says "you're missing out if you don't get these".
