To wear this shirt, simply put it on like any other long - sleeve shirt. It's great for casual outings or a more laid - back work environment. When it comes to care, you can machine - wash it on a gentle cycle with cold water to keep the spandex in good shape. Avoid using harsh detergents as they might damage the fabric. After washing, tumble dry on low heat or hang it to dry. Before buying, always double - check the size chart because different suppliers may have slightly different sizing. And if you spill something on it, try to clean it as soon as possible to prevent stains from setting.
