How to take my measurements??

The attached photo clearly shows taking a measurement with a tailor's tape measure:

Here's exactly how to determine your size:

1. Take a tailor's tape measure (you can also use a string here, which you then measure with a tape measure).
2. Place the tape measure approximately 2-3 cm above the eyebrows.
3. Circle the tape measure around your head, precisely reaching the most prominent part of the head.
4. IMPORTANT! This is a measurement for standard hat wearing!
