re: #27 marjoriemoon
I’d have to disagree that it wasn’t common among my grandmothers’ generation (one was born in 1890, the other in 1905). I probably have as many pictures of them them wearing scarves outside the home as I have where they aren’t. I suspect some of it was culture related, but mostly it was probably to keep the wind from blowing those up-dos around.
Of course, the scarf/cap style was quite popular in the 60s (think Jackie O).
Until the 1960s, rigid custom (but not theology) required that Catholic women wear a head covering any time they entered a church. There are still vestiges around the world
