To wear this shirt, simply button it up through the single - breasted closure and adjust the stand collar for a neat look. This shirt is suitable for various casual and semi - formal occasions. When it comes to washing, it's best to use a gentle cycle in cold water to preserve the quality of the polyester fabric. Avoid using harsh detergents as they may damage the fabric. After washing, let it air dry instead of using a dryer to prevent shrinkage. Always double - check the size chart before purchasing to ensure you get the perfect fit for your body.
