This Halloween hoodie is super easy to use. Just put it on and you're ready to show off your cool style! When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size as our sizing runs a bit smaller compared to the USA standard. Check the size chart for exact measurements. To keep your hoodie in great shape, machine wash it in cold water using a gentle cycle and mild detergent. After washing, hang it up to dry. Don't worry if there are minor differences in the measurements or a slight color variation between the screen and the actual product. These are normal and won't affect your enjoyment of this awesome hoodie.
