To wear this sweater, simply slip it on over your head. It's great for casual outings or just lounging at home. When it comes to washing, it's best to use a gentle wool detergent and hand - wash it in cool water. Avoid wringing the sweater to prevent it from losing its shape. After washing, lay it flat to dry. Store it in a cool, dry place, and you can use a moth - repellent to keep it in good condition.
