To wear these leggings, simply step into them and adjust the elasticated waistband for a comfortable fit. They're great for lounging at home during fall, so you can pair them with the matching sweater for extra coziness. When it comes to washing, use a gentle cycle in cold water to keep the fabric in good condition. Avoid using harsh detergents as they might damage the anti - pilling acrylic. After washing, lay them flat to dry to prevent any stretching. And remember, these leggings run true to size, so choose the size you normally wear.
