Using this hoodie is super easy. Just put it on and you're ready to go out looking stylish! When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size as the international sizing we use is a bit smaller than the USA standard. Check our size chart to get the most accurate fit. For cleaning, simply toss it in the washing machine in cold water on a gentle cycle with mild detergent. After that, hang it up to dry. Keep in mind that the measurements are approximate, so there might be small differences. Also, don't be surprised if the color on your screen looks a bit different from the real hoodie because of monitor settings.
