we're forgetting that we all have more clothes than most people had then, and nobody wore sweats or jeans at home. so, I am guessing that it was only recently that people changed all their clothes when they walked in the door. they took off their jacket and maybe tie, and maybe put on a smoking jacket, robe or cardigan. or, if they didn't have those, they left on their jacket, too. my father, when I was little and he wore one to work, would leave on his dress shoes, pants, shirt and tie until pretty much he went to bed. he would take off his jacket when he got home.
