This awesome hoodie is super easy to wear. Just slip it on over your head and you're good to go! When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size because the international sizing is smaller than the USA standard. Check the size chart for the most accurate fit. For cleaning, simply throw it in the washing machine on a cold, gentle cycle with mild detergent. After that, hang it up to dry. Keep in mind that the colors on your screen might look a bit different from the real hoodie because of monitor settings, and the measurements might have a little bit of variation.
