To wear this sweater, you can simply pull it over your head. It looks great on its own or layered with a light jacket. For a casual weekend, team it up with white jeans as mentioned. When it comes to care, it's best to machine - wash it in cold water on a gentle cycle. Avoid using harsh detergents as they might damage the linen fabric. Hang it to dry to keep its shape. And store it in a cool, dry place when not in use.
