To use these leggings, simply put them on like regular leggings. The elastic waistband makes them easy to pull up and down. For casual days, wear them with a simple top and sneakers. For a more put - together look, pair them with the matching jacket and some nice shoes. When it comes to maintenance, machine wash them in cold water with like colors. Avoid using bleach as it may damage the fabric. Tumble dry on low to keep them in good shape. And remember, don't iron the piped trims directly to prevent any damage.
