This Santa Claus Christmas hoodie is super easy to use. Just put it on and enjoy the comfort. When it comes to sizing, remember to order 1 - 2 sizes larger than your usual size as the international sizing is a bit smaller. For cleaning, simply toss it in the washing machine in cold water on a gentle cycle with mild detergent, then hang it up to dry. Be aware that the color you see on your screen might be a bit different from the actual hoodie, and there could be a small measurement error because it's hand - measured.
