This doesn't have a materials tag, but feels like a midweight cotton or poly blend, not wool. Cardigan does have a button front placket, but buttons are decorative and do not secure the front. Sweater is in good pre-owned condition, with some light wear near cuffs, and a few small holes (nape of neck and another that are shown in photos). Still a really cute piece, but price has been marked down to reflect condition! Please review photos for additional details and measurements, and let me know if you have any questions! Thanks for looking, and check out my other closet listings if you'd like to bundle and save 💕
