To wear this sweater, simply pull it over your head. It goes great with jeans for a casual day out or can be layered under a blazer for a more dressed - up look. When it comes to care, it's best to machine wash it in cold water on a gentle cycle. Use a mild detergent. Avoid using bleach as it may damage the fabric. After washing, reshape the sweater while it's still damp and lay it flat to dry. This will help maintain its shape and prevent stretching. If you need to iron it, use a low - heat setting to avoid any damage to the garter stitch pattern.
