To use this tee, simply put it on and enjoy your day. It's great for casual outings or light workouts. 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 graphic print. Hang it to dry or tumble dry on low to prevent shrinking. This tee is made to order, so be patient during the 7 - 10 business day processing time. With proper care, it will last you a long time.
