During the first score of your life, your hats shall be gray, during your first score and ten, the color you shall wear is black and unveiled. The second score and later, our most grand years, while wearing the black hat, that is now veiled, the embellishments grow larger.

The hats we wear reflect the year and stylings of our anachronistic lives.
Bonus, if when you are out with the rest of the women of the Society. You wear clothing that goes with your hat!
