@Olivier5,
I once knew this woman, in her I guess 20’s at the time, who always wore a bra. She wasn’t large breasted. It was I think out of modesty. I wondered what her husband thought of that, but I guess he didn’t mind. According to her he had never seen her without one.
Off topic, but I also knew a young woman who said her father had never seen her mother’s hair, as she always wore wigs, and had particular ones for bed.
