I don't own any. Haven't in 30 years. . Once in a store, I looked at some (was looking for socks and came across underwear) had no idea there were so many different styles, and man is it expensive. . When I go to the doctors, and they say "strip to your underwear" I tell them "I don't wear any" and they give me a paper gown. Even when its 10 below here, I'm never outside long enough to get that cold. Seems like a waste of money to me. We shower every day and stay clean, so why bother.
