How to Use: These shirts are very versatile. You can wear them buttoned up for a formal look, or leave a few buttons undone for a more casual style. They pair well with jeans, chinos, or dress pants. Note: Always check the size chart carefully before making a purchase as sizes may vary between different suppliers. Maintenance: Machine wash these shirts in cold water on a gentle cycle. Use a mild detergent and avoid bleach. Hang them to dry to keep their shape. Iron on a low setting if needed.
