To use this tee, simply put it on like any other shirt. It's perfect for casual outings or just lounging at home. When it comes to washing, you can toss it in the washing machine on a gentle cycle with similar colors. Use a mild detergent to keep the colors vibrant and the fabric soft. Avoid using bleach as it can damage the low - impact dyes. Hang it to dry or tumble dry on low to prevent shrinkage. Although it's pre - shrunk, high - heat drying might still cause some minor shrinkage. Iron it on a low setting if needed, and be careful around the design area to protect the heat transfer. Enjoy your new, comfortable tee for years to come!
