To use this sweatshirt, simply put it on and enjoy the warmth and comfort it provides. It's suitable for various casual occasions. When it comes to washing, use cold water and a gentle cycle to keep the colors bright and the fabric in good shape. Avoid using bleach as it may damage the design. Hang it to dry instead of using a dryer to prevent shrinkage. If you need to iron it, set the iron to a low - heat setting. And remember, since it's made to order, it will take 7 - 10 business days to process before it reaches you.
