This hoodie is really easy to use. Just put it on and enjoy its comfort. When it comes to washing, you can either hand - wash or machine - wash it. But remember, the colors won't fade or crack because of the advanced printing technology. As for sizing, it runs 1 size smaller than USA size, so if you like a looser fit, order 1 - 2 sizes up. Also, don't be surprised if the color on the screen looks a bit different from the real hoodie due to monitor settings. Take good care of it, and it will serve you well for a long time.
