To use this uniform shirt, simply put it on as you would with any other shirt. The long tail is designed to stay tucked in, so make sure to tuck it in properly at the start. When it comes to maintenance, you have two options. You can either machine wash it or take it to a dry cleaner. It's also suitable for industrial laundries. As for the collar stays, they are permanent, so there's no need to worry about them falling out. When using the pockets, you can use the pen opening in the left pocket to keep your pen handy. Just be careful not to overstuff the pockets as it might affect the shirt's appearance. If you want to use shoulder loops, unbutton the cross - stitched epaulets. That's it! With proper care, this shirt will serve you well for a long time.
