We recommend that your shirt gets a nice cool wash at 30 degrees.
Please, do not tumble dry. Hang it out and let it dry el-natural!
You can iron your shirt, sure, but on a low tempreature, maybe as advised by your iron for wool/acrylic. If in doubt iron your shirt through an empty pillowcase to protect the fabric.
Our shirts are Made in Istanbul for you in Blighty - 80% Acrylic & 20% Polyester
