To wear this T - shirt, simply slip it on over your head. It's great for casual outings like hanging with friends or going to the park. When it comes to care, machine wash it in cold water to keep the colors bright and the fabric in good shape. Don't use bleach as it can damage the polyester and spandex blend. Hang it to dry to prevent any shrinking. Since sizes can vary by supplier, always double - check the size chart before making a purchase to ensure a perfect fit.
