Taking your measurements
If you want to wear your hat correctly on your head, make sure you know your size. It’s very simple: just measure the contour of your head. Use a tape measure to go around your head, starting at your forehead and going just above your ears. If in doubt, ask someone you trust for help, someone who won’t make you lose your head.
