To use this sweatshirt, simply put it on and enjoy the warmth and style. It's suitable for casual outings or staying at home. When it comes to washing, use a gentle cycle with cold water to keep the colors and fabric in good condition. Avoid using bleach as it may damage the graphic. Hang it to dry to prevent shrinking. Since it's made to order, please be patient during the 7 - 10 business day processing time. Also, the spandex in the collar, cuffs, and waistband means it may stretch a bit over time, but it will still retain its shape well.
