Using this shirt is a breeze. Just put it on and style it however you like, whether it's with jeans for a casual look or with dress pants for a more formal occasion. When it comes to washing, turn the shirt inside out to protect the printed letters. Wash it in cold water on a gentle cycle to avoid shrinking or fading. Use a mild detergent and don't bleach. Hang it to dry or tumble dry on low. As for sizing, always refer to the size chart carefully as different suppliers and brands may have variations. This way, you'll ensure a perfect fit and keep your shirt looking great for a long time.
