To use this shirt, simply button it up and you're ready to go for work or travel. When wearing, adjust the buttons according to your preference for a more comfortable fit. As for care, it's best to machine wash it in cold water to keep the color and fabric in good condition. Avoid using bleach as it may damage the wrinkle-free finish. After washing, tumble dry on low to prevent shrinkage. Iron on a low setting if needed, but be careful around the contrast collar and cuffs to maintain their look.
