The Red Hat Society is indeed alive and well. My late GMIL was a member. A few years back, I was visiting a winery for a wine tasting, and in came a group from the Red Hat Society - one of them was wearing a foam lobster as her red hat!
I'm not a hat person. I wear my hair long and loose at home and in social situations. When I'm at work or working in my garden, I tie my hair back in a bun or ponytail.
When I was a rho chi (yes, I was a rho chi in the days when rho chis were called rho chis) we were required to wear hats so that we could be easily identified by rushees. I borrowed a straw hat from my mother.
