Bet you one time Prussia posted some fake law about restricting nudity in Germany's house - like, in their literal house that they live in - as a prank, and then Germany took it seriously for an hour and was almost set on petitioning their boss and shit and then Prussia had to fess up to it because even he could not bear the idea of Germany explaining to Merkel the health benefits of regularly airing the nation personification's testicles.

Let's see, Greece I think would be fine with it - or rather, he doesn't give a shit either way. Spain, certainly. Turkey too (he seems to cover up in public but I'm sure he likes lounging in the nude and gossiping with other old dudes in those baths, he's pretty chipper about that waiter outfit and I think he didn't give a fuck during that new year's event either). America's always been gung-ho in skimpy outfits. England when drunk apparently answers the telephone nude, if I remember that old note right? …I really, really think Austria likes the idea too but simultaneously wants to make it look as though he was put up to it. I mean come on the only ghost he can dress up as is a naked pervert ghost? Don't lie Austria, we've got Google.

What about you, anon, any nudity theories/headcanons? :D
