If I saw someone walking around in PJs I'd probably say something about it to my husband when he got home at night.
But if I were wearing something unusual I would expect people might comment about it. For instance, I went bald in high school.
I am sure people talked about it, but as long as they weren't saying anything to my face, some people really did and were asses, why should I care?
I'll never know them, I can't control them and I will never find out about it.
