To wear this t - shirt, simply put it on like you would any regular shirt. It's great for casual outings, work, or even just lounging at home. When it comes to washing, use a gentle cycle in cold water to keep the colors vibrant and the fabric in good condition. Avoid using harsh detergents that could damage the polyester and acrylic blend. After washing, lay it flat to dry to prevent any shrinking or stretching. As for ironing, set your iron to a low - medium heat to avoid melting the synthetic fibers. Always check the size chart carefully before purchasing to ensure the perfect fit. And remember, different suppliers may have slightly different sizing, so take your time to choose the right size for you.
