These men's casual shirts are great for everyday wear. To put them on, simply slip them over your head and button them up. When choosing a size, remember to check the size chart as different suppliers may have different sizing. If it's an Asian size, it's better to go a size up. For maintenance, these shirts made of polyester and spandex are easy to care for. You can machine - wash them on a gentle cycle with cold water. Avoid using bleach as it may damage the printed pattern. After washing, hang them up to dry to keep their shape. The turn - down collar and single - breasted closure give a classic look, and the regular sleeve style provides a comfortable fit. Wear them with jeans for a relaxed look or pair them with khakis for a more dressed - up casual style.
