I remember bed jackets. Last time I wore one was when I had my first child, that was 55 years ago! It was soft and frilly and wore it over my nightgown so I was 'presentable' for getting out of bed, doctor's exams and visitors.
Nowadays I tend to wear old sweats or knits as my pj's, so convienent and I'm able to go out doors if necessary say to throw out the trash or get the mail.
