To wear this shirt, simply button it up through the single-breasted closure. You can pair it with jeans for a casual look or with dress pants for a more formal occasion. When it comes to maintenance, it's recommended to machine wash it in cold water on a gentle cycle. Avoid using bleach as it may damage the fabric and fade the geometric print. Hang it to dry to prevent any shrinking or warping. Before ironing, make sure to set the iron to a low or medium heat setting to protect the polyester material. Also, always check the specific size chart for this shirt as different suppliers may have variations, so you can choose the size that fits you best.
