To wear this shirt, simply button it up using the single-breasted closure. You can pair it with jeans for a casual look or dress pants for a more formal occasion. When it comes to care, machine wash it in cold water with like colors. Avoid using bleach as it may damage the floral print. Hang it to dry to keep its shape. As for sizing, always refer to the size chart since different suppliers and brands have their own measurements. If you're in between sizes, it's better to go for the larger one for a looser fit.
