To wear this sweater, simply pull it over your head. It looks great with jeans for a laid - back weekend look or with dress trousers for a more formal occasion. When it comes to care, it's best to machine wash it in cold water on a gentle cycle. Avoid using bleach as it can damage the cotton and fade the colors. After washing, reshape the sweater while it's damp and lay it flat to dry to prevent stretching. If needed, you can iron it on a low - heat setting, but be careful around the contrasting stripes to keep their sharp look.
