To use this sweater, simply put it on like any other pullover. You can style the attached scarf in different ways - you can let it drape over your shoulders or wrap it around your neck for extra warmth. When it comes to washing, it's best to follow the care instructions on the label. Usually, a gentle cycle in cold water with a mild detergent is a good idea. Avoid using bleach as it can damage the fabric. Hang it to dry instead of putting it in the dryer to prevent shrinking. Also, make sure to check the size chart before purchasing. Different suppliers and brands may have different sizing, so pick the size that fits you best. This way, you'll be able to enjoy your sweater for many winters to come.
