Available in four timeless colourways (raisin, charcoal, deep brown and mid grey) they will pair effortlessly with your autumn/ winter wardrobe.

RRP: £35
Sizes: 6-22

Leggings make for a stylish, effortless outfit option when off-duty dressing, especially on busy weekends when speed and convenience is key. The trick to wearing them as cold-weather outerwear is to ensure they’re substantial enough to stand up against chilly winds, and thicker jegging styles do just that. A hybrid of jeans and leggings, jeggings have all the durability and versatility of the former with the comfort and stretch of the latter, making them a quick and easy piece to throw on in the mornings. White Stuff’s Jodie Ponte Jeggings come in classic dark indigo and black, with a flattering high-waisted and ankle-grazing, slim-fit silhouette.

Made from a combination of soft cotton and premium, temperature-regulating merino wool, they guarantee all-day warmth and supreme comfort.
