To wear this sweater, simply zip it up using the front zipper. It's great for daily activities, whether you're going to work, running errands, or meeting friends. When it comes to maintenance, you can machine - wash it in cold water on a gentle cycle to keep the colors and shape intact. Avoid using harsh detergents as they might damage the fabric. After washing, reshape it gently and let it air - dry. Don't hang it on a thin hanger as it could stretch out the shoulders. As for sizing, always check the size chart carefully because different suppliers have different measurements. If you're between sizes, it's usually better to go for the larger one for a more comfortable fit.
