What is the one thing you don't really need?
underpants
I am in agreement with this one. Back when clothes were made mostly of rough wool, you needed underpants to avoid chaffing. But, assuming you clean yourself properly after using th facilities, with today's clothing made with modern fabrics you don't really need underpants anymore.
@snytiger6 yep. I haven't owned underwear since the 90's.
@kauva I own underwear and will put it on if I am to go shopping to try on clothes. But, that is the only reason I might wear it.
