To wear this shirt, simply button it up through the single-breasted closure. You can pair it with a suit for a formal business look or with jeans for a more casual style. When it comes to washing, follow the care instructions on the label. Usually, it can be machine - washed in cold water to keep the color and fabric in good condition. Avoid using harsh detergents as they may damage the polyester and spandex blend. After washing, reshape the shirt while it's still damp and lay it flat to dry to prevent shrinkage. Check the size chart carefully before purchasing to ensure you get the right fit, as different suppliers may have variations in sizing.
