Obsolete Clothing Items
Over the past 50 or so years, men's pajamas seem to have all but disappeared. At the same time, women's slips petticoats etc.have become virtually nonexistent. Even mens jackets and ties have gone from commonplace to rare.
Any one think men's underwear will at some point have the same fate?
PJs are going because more guys are wearing shorts/underwear or nothing to bed. Its just more common. Underwear will never go, its necessary to wear most of the time if you are active or if its hot out. Plus I would rather not wear sweatpants without underwear anywhere but home...
I wore underwear less often I in hot weather than other times before I stopped completely.
I doubt that underwear will ever go away. Though I sleep nude and live nude when possible, when I am clothed I wear briefs. For me it is just more comfortable to have the boys restrained a bit.
As we get older and the plumbing gets less reliable underwear is handy.
My wife uses it to hold a small pad in place when she needs it and I wear a small cotton g-string when I'm on a long journey, especially if wearing light coloured trousers.
