To use this cardigan, simply put it on over your outfit. It's great for adding a layer of warmth and style. You can keep small items like keys or your phone in the side pockets. When it comes to care, it's best to follow the washing instructions on the label. Usually, a gentle machine wash with cold water and air drying is a good way to keep it in good shape. Avoid using harsh detergents or bleach. Also, be careful not to over - stretch the fabric when putting it on or taking it off.
