This hoodie is super easy to wear. Just slip it on over your head and adjust the hood as you like. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size because our sizing is a bit smaller than the USA standard. Check the size chart for the best fit. For washing, you can 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 measurements are approximate, so there might be small differences. Also, the color on your screen might not be exactly the same as the real hoodie due to monitor settings.
