These knit pants are for spring, summer, and autumn. They are crocheted, and have a petticoat (lining) above the knee. The crochet pattern is different above and below the knee, which is cute. These are used items, so please refrain from purchasing if you are concerned. I have a lot of women's apparel, baby clothes & kids' clothes for sale at #ぷしゅのお店.
