To use this sweatshirt, simply put it on like any regular top. It's great for casual outings or staying at home. As it's made to order, please be patient during the 7 - 10 business days processing time. When it comes to washing, use a gentle cycle with cold water to keep the fabric and design in good condition. Don't use harsh detergents as they might damage the soft - feel heat transfer design. Hang it to dry to prevent shrinkage. Also, avoid ironing directly over the design to maintain its quality.
