This stylish shirt is great for daily wear during the summer. To put it on, simply open the single - breasted closure and slip it over your head. Button it up and adjust the turn - down collar to your liking. Since it has a short sleeve length, it keeps you cool in the warm weather. When it comes to sizing, always refer to the size chart as different suppliers and brands may have variations. For washing, use a gentle cycle in cold water to preserve the fabric made of polyester and spandex. Hang it to dry to avoid any shrinkage. Iron it on a low - heat setting if needed to keep it looking sharp.
