My Mum wore headscarves and always had one in her handbag together with a plastic rain hood. She also wore a headscarf, tied WWII style, to protect her hair when doing housework or decorating. My GM never wore a headscarf, thought they were 'common'.
I have worn headscarves in open top cars, or walking along windy seafronts when on holiday.
I was a far from an obedient girl/woman but I did agree to obey in my wedding vows simply because I'm quite traditional. But in over 40 years of marriage my obedience has never been requested, it's never been necessary, but if it ever was I'd be obeying out of love and respect for my husband not because of the vow I had taken.
