To wear this shirt, simply button it up through the single - breasted closure. The turn - down collar gives it a casual look, so you can wear it open for a more relaxed vibe or buttoned up for a neater appearance. When it comes to maintenance, since it's made of cotton, it's best to wash it in cold water to prevent shrinkage. Use a mild detergent and avoid bleach. Hang it to dry to keep its shape. And don't forget to check the size chart carefully before purchasing, as different suppliers may have different sizing standards.
