I bought a bunch of big headband-type things from Amazon. The are really versatile and come in male and female colors, and are stretchy.
If they start requiring them I am just going to wear one around my neck and pull it up when I go out. I will look like a Wild West bandit, but at least it is something.
What’s a ‘male’ or ‘female’ color?
(Excluding pink and lavender, of course...)
