Using this shirt is easy. Just slip it on and you're ready to go for a casual outing. When it comes to washing, you can machine - wash it in cold water on a gentle cycle. This helps to keep the fabric in good condition and prevent any shrinkage. Avoid using bleach as it might damage the polyester fiber. After washing, tumble dry on low heat or hang it to dry. Before wearing it again, you can iron it on a low - heat setting to make it look neat. Also, always double - check the size chart before purchasing to ensure the best fit for you.
