To wear this shirt, simply button it up and adjust the collar for a neat look. You can pair it with jeans for a casual day out or with dress pants for a more semi - formal occasion. When it comes to washing, it's best to follow the care label instructions. Usually, you can machine - wash it in cold water on a gentle cycle. Avoid using harsh detergents as they may damage the fabric. After washing, hang it to dry to maintain its shape. Before ironing, set your iron to a low - heat setting to prevent any damage to the polyester - spandex blend. And always double - check the size chart before purchasing to ensure you get the right fit.
