This couple hoodie is super easy to use. Just put it on and enjoy the comfort. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size because the international sizing is a bit smaller than the USA standard. If you're a woman, you can order a smaller size. As for maintenance, it's quite simple. Machine wash it in cold water using a gentle cycle and mild detergent. Then, just hang it up to dry. Keep in mind that the color you see on your monitor might be a little different from the actual hoodie, and there could be a small measurement difference because it's hand - measured.
