If line drying, put the shirt on a hanger and button the placket. The collar should be folded down. Smooth it with your hands. If the shirt is cotton, you may want to dry it on a drying rack so that it doesn’t shrink. [3] X Research source

If the fabric is cotton or polyester and your shirt isn’t still damp from washing, put your iron on a steam setting or have a spray bottle of water ready to dampen the shirt. Don’t use steam if the fabric is silk. Test iron a small piece of fabric on the inside bottom hem before you fully iron your polo shirt. If the high temperature seems too much for the fabric, lower the iron’s temperature.
