To use this sweatshirt, simply put it on like any other top. It's suitable for various casual occasions, like hanging out with friends or watching a movie at home. When it comes to washing, turn it inside out and use a gentle cycle in cold water. This helps to protect the graphic and the fabric. Avoid using bleach as it can damage the color and quality of the sweatshirt. After washing, it's best to tumble dry on low heat. If you want to iron it, use a low - heat setting and iron on the reverse side to prevent any damage to the design.
