I have always slept in the nude as a adult until I had my kids. Then I opted for the tank top undies. Now that they are getting older and do not tend to crawl in bed with me in the middle of the night often. I have reverted back to sleeping topless on most nights.
But I hate cloths I will walk around all day in a tank top and undies if I don't have to go anywhere sorta explains my $300.00 electric bill this month.

I do not recall my H ever sleeping totally nude. He has started to sleep in just his drawers over the years. But use to sleep fully clothed. Sweatpants and T shirts and all.
