Yes I know that armor was more than obsolete at the time, but that's the impressive thing, how nobles kept the fashion of having one, which is even seen in the first post. But yeah, really have no knowledge of how often they wore one. Probably on very special parades or just for portraits, last one with armor dating all the way up to 1730, although I'm not entirely sure who was the person wearing it.
So yeah, I actually doubt we'll be seeing officers commanding armies in plate or wearing it on the streets, but who knows, that's why I asked the question
But hey, after seeing how detailed the mod is, I wouldn't be surprised if there was one in some special shop or on some noble's wall.
