The affordable £25 M&S jeans to know about (Marks and Spencer/Yahoo Life UK)

The hunt for the perfect pair of flattering, affordable jeans is officially over, thanks to our latest discovery of Marks & Spencer's Sienna Straight Leg Jeans with Stretch. The original Sienna Jeans first launched in 2019 and were so popular that a pair sold every minute. To make them even better, M&S gave the style an update in 2022 for additional comfort and flexibility by creating the same style with extra stretch.

At a mere £25, it's no wonder they're often sell out, but luckily, there has recently been a restock. Boasting over 5,000 five-star reviews, they're currently the most popular pair of jeans on M&S's website, so add them to your basket ASAP if you're in the market for a new pair.

Thousands of M&S shoppers are raving about this stretchy straight-leg pair of jeans.

Why we rate it

These jeans boast a flattering straight leg cut (which works well with shirts tucked in or out) and feature a mid-rise waist that is a blessing if you're conscious of your tummy, which high-waisted styles can often highlight.

They are also made from super-stretchy fabric for all day comfort, so you can sit down and work in them without having them digging into you.

Doubt any pair of jeans could be that comfy? The reviews speak for themselves with customers remarking that these are "the most comfortable jeans I have ever owned". In fact, many women are purchasing multiple pairs, one shopper even said they have now "bought them in every colour".

What the reviews say
