To wear this hoodie, just put it on like any regular hoodie. It's great for casual outings or relaxing at home. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal one for a better fit. As for maintenance, use cold water and a gentle cycle on your washing machine with mild detergent. After that, hang it up to dry. Keep in mind that the color might look a bit different on your screen compared to the actual hoodie, and there could be a small measurement difference because it's measured by hand.
