The hunt for the perfect pair of flattering, affordable jeans is officially over. And we can thank the unofficial high street jeans supremo, Marks and Spencer.

M&S consistently launches the kind of jeans styles that suit 'real' women (i.e. not slim 16-year-olds with endless legs that many brands seem to build their denim ranges around.)

From their sell-out magic jeans that give you incredible shape to these Mom Jeans loved by Holly Willoughby, the design team at M&S know what we want and what works for us.

However, there's one style that has really caught our attention: The Sienna Straight Leg Jeans with Stretch.

The original Sienna Jeans first launched in 2019 and were so popular that one pair sold every minute.

To make them even better, M&S gave the style an update for additional comfort and flexibility by creating the Sienna Straight Leg Jeans with Stretch. At a mere £22.50 any wonder they're flying off the virtual shelves.

Why we rate it

These jeans boast a flattering straight leg cut (which means you can wear your shirts tucked in or out without looking huge) and a mid-rise waist (a blessing if you're conscious of your tummy which high-waisted styles can often highlight).

They are also made from super stretchy fabric, so you can sit down and WFH in them all day without getting those 'denim welts' on your tummy.

Doubt any pair of jeans could be that comfy? The reviews speak for themselves with customers remarking that these are "the most comfortable jeans [they] have ever had", with many women purchasing multiple pairs.

What the reviews say

With over 5,500 reviews from shoppers, it's safe to say the Sienna Straight Leg Jeans with Stretch are an incredibly popular – and affordable – investment, hence many are stocking up and buying up the jeans in other colourways, too.

  • "These are the perfect jeans for fit, quality and comfort."

  • "Very pleased with the fit and variety of colours of these jeans. I’ve now bought 4 pairs. I’m size 10, 5ft 3in and size 10 short are a perfect fit and length."

  • "Lovely jeans, excellent value. Good fit. Comfortable. Not too stretchy."

  • "Best jeans ever! The stretch in the jeans gives a great fit and they are the most comfortable I have ever had. Will be buying in other colours."
