This hoodie is really easy to use. Just put it on and you're ready to go! Whether you're going out for a walk, hanging out with friends, or just relaxing at home, it's a great choice. When it comes to washing, you can either hand - wash or use a machine. But remember, the colors won't fade or crack because of the advanced printing technology. As for sizing, since it's 1 size smaller than US sizes, if you want a loose fit, order 1 - 2 sizes up. And don't be surprised if the color on the screen looks a bit different from the real thing, that's just because of the monitor settings. Take good care of it, and it'll last you a long time.
