To wear this sweater, simply pull it on over your head. It's great for casual days out or more laid - back work environments. You can wear it on its own in mild weather or layer it under a jacket when it's colder. When it comes to washing, it's best to follow the care instructions on the label. Usually, a gentle cycle in cold water and air - drying is a good way to keep it in great shape. Avoid using harsh detergents as they may damage the lurex stripes. Also, be careful not to snag the sweater on sharp objects to keep it looking new.
