To use this tee, simply put it on like any other shirt. It's great for everyday wear, sports, or casual outings. When it comes to washing, use a gentle cycle with cold water and mild detergent. Avoid using bleach as it may damage the fabric and the graphic print. Hang it to dry or tumble dry on low to maintain its shape. For ironing, use a low heat setting. If you plan to do sublimation printing on it, follow the standard printing instructions for polyester fabrics.
