Why we rate it
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", while another said "I have bought 7 pairs now."
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.
