These men's casual plaid shirts are great for daily wear. Just put them on like any regular shirt. When choosing a size, make sure to check the size chart carefully as different suppliers may have different sizing. If it's an Asian - sized shirt, go for a bigger size. To keep your shirt in good condition, machine - wash it in cold water on a gentle cycle. Hang it to dry to prevent shrinking. Iron it on a low - heat setting if needed. Avoid using harsh detergents that could damage the fabric.
