The hunt for the perfect pair of flattering, affordable jeans is officially over, thanks to 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.

Quick overview

At a mere £25, it's no wonder they often sell out, but luckily, there has recently been a restock. Boasting over 6,400 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.

These jeans boast a flattering straight leg cut (which works well with shirts tucked in or out) and features a high-waist design that is super versatile and makes the jeans easy to dress up or down.

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".

With over 6,000 five-star reviews, it's safe to say there's lots to love about them. (Marks & Spencer)

£25 at M&S

The hugely popular jeans come in eight colours including dark indigo, black and white, so you're bound to find just the shade you're looking for. What's the most popular? Well, the dark grey hue have been such a hit they have already sold out.

The jeans also come in sizes 6 to 22 and with a number of leg length options, from petite to extra long, so you don't need to worry about the jeans coming up short.

As the winter chill sets in, our styling tip is to throw on some jeans with a trendy button-up cardigan featuring statement buttons. M&S's new Crew Neck Cardigan is proving very popular right now, as it looks super luxurious and is the perfect elevated knit for the colder months. It also comes in three colours: cream, grey, and red.

This smart but cosy cardigan is perfect for your winter wardrobe. Available in cream, red and oatmeal, it has a luxe gold button-up design so you can wear it open with a t-shirt or done up on its own.

Due to their popularity, M&S gave the Sienna Jeans an update in 2022, launching the more expensive Sienna Supersoft Straight Leg Jeans, which are £32.50, and are made with an extra soft material for additional comfort and flexibility. Having racked up over more than 1,500 glowing five-star reviews from shoppers, they're also a popular pick you may want to check out.

These super soft and stretchy straight-leg jeans are flying off shelves, with rave reviews from shoppers.

With over 6,4000 five-star reviews from shoppers, it's safe to say the Sienna Straight Leg Jeans are an incredibly popular – and affordable – investment, hence many are stocking up and buying up the jeans in other colourways, too.
