To use this shirt, you can choose to tuck it into your 24-7 Series pants for a more formal look when on duty. Or, leave it untucked for a casual style during your off - duty time. When wearing it, make sure the pen/pencil stall is handy for keeping your writing tools. For the hidden document pockets, use them to store small important papers safely. As for maintenance, machine wash it in cold water with like colors. Avoid using bleach as it may damage the fabric. Hang it to dry to keep its shape. Check the zipper and hook & loop closures regularly to ensure they are in good working condition. If there are any loose threads, trim them carefully to prevent further fraying.
