Using this hoodie is super easy. Just put it on and enjoy the comfort! When it comes to sizing, since our international size is usually smaller than the USA standard, order 1 - 2 sizes larger than your normal one for a better fit. For maintenance, simply throw it in the washing machine in cold water on a gentle cycle with mild detergent. Then hang it up to dry. Remember, the color you see on your screen might not be exactly the same as the actual hoodie because of your monitor. Also, there might be a small measurement difference because it's hand - measured.
