To use this sweatshirt, simply put it on and enjoy the cozy warmth. When it comes to washing, use a gentle cycle with cold water and mild detergent. Hang it to dry to maintain its shape. Avoid using bleach as it can damage the design. Since it's made to order and takes 7 - 10 business days to process, be patient while waiting for your custom sweatshirt. The spandex in the collar, cuffs, and waistband might stretch a bit over time, but it should bounce back. And don't worry about the faux - sequin design, it's made to last through regular wear and washing.
