Specifications
RRP: £35

Leggings make for a stylish, effortless outfit option when off-duty dressing, especially on busy weekends when speed and convenience is key.

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.
