This Duke sweater is super versatile. You can wear it on formal occasions by pairing it with dress pants and dress shoes, or for casual outings with jeans and sneakers. When it comes to washing, it's best to use a gentle cycle in cold water to keep the fabric's softness. Avoid using bleach as it might damage the wool. After washing, reshape it gently and lay it flat to dry. Iron it on a low - heat setting if needed. Store it in a cool, dry place, and it will last you a long time.
