How to use: Just put on the shirt like you would with any other button - down shirt. Button it up starting from the bottom, and adjust the collar and cuffs as you like. You can roll up the sleeves easily thanks to the adjustable cuffs. Notice: Avoid wearing it in extremely harsh environments that could damage the fabric. When washing, follow the care label instructions. Maintenance: Wash it in cold water with mild detergent. Hang it to dry to keep its shape. If needed, you can iron it on a low - heat setting.
