Using this shirt is a breeze. Just put it on like you would any other shirt. It's suitable for a variety of occasions, from a day at the office to a weekend picnic. When it comes to sizing, always check the size chart carefully as different suppliers and brands may have variations. For maintenance, you can machine - wash it in cold water on a gentle cycle. Use a mild detergent to keep the fabric and the pattern in good condition. Avoid using bleach as it may damage the print. Hang it to dry to prevent any shrinking or warping. Iron it on a low - heat setting if needed, but be careful around the collar and cuffs to keep their shape.
