To wear this sweater, simply slip it on over your head. It looks great with any pair of denim you have in your closet. For accessories, you can choose something that matches the navy color, like a brown belt or a pair of blue - toned sunglasses. When it comes to maintenance, it's best to wash it in cold water on a gentle cycle. Hang it up to dry to keep its shape. Avoid using bleach or harsh detergents as they might damage the contrast stitch detailing. Also, store it folded in your dresser or closet to prevent any stretching.
