If you lived alone 10 miles from the closest neighbor and rarely left your property, went outside, or had company, would you wear heels, stockings, shape wear, wigs, dresses, makeup, shave legs, shave face as often as you do now?
I think that most people would settle into a routine that required the least amount of effort to achieve a comfortable, practical, lifestyle.
I am presently home alone for the weekend. I could wear anything I want right now. I choose slippers over heels, and a robe and lounge pants over hose and a dress. I think if I were alone all the time, I would not shave and would choose my clothing based on most comfortable, most practical, easiest to put on, easiest to clean and least expensive. I would find the most comfortable clothing that kept me warm in winter and cool in summer.
Some people today go out in public in pajama's and slippers.
I think older people are into comfortable clothing. Often times older people shower much less often than they did when they were younger. It is standard practice in long term nursing homes to shower the elderly only once a week.
I think that most people left alone would opt for comfort over glamour.
