This hoodie is super easy to use. Just slip it on and enjoy the comfort and style it brings. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal one to ensure a great fit. As for maintenance, machine wash it in cold water using a gentle cycle and mild detergent. Then hang it up to dry. Also, be aware that the color you see on your monitor might be a bit different from the actual hoodie, and there could be a small measurement difference because it's hand - measured. Keep these things in mind, and you'll be able to enjoy your hoodie for a long time.
