Oh! Can you talk more about the "tuberculosis chic" myth? That's one I had thought was true
Sure!
There's not really much to it except "no, people were not trying to look like they had tuberculosis; tuberculosis symptoms mimic beauty standards that had been around for centuries at that point and it led to the disease being romanticized." Which seems like a minor difference, but it strikes me as one more "oh, those weird alien people in the past (specifically women, who as everyone knows are stupid and will do anything for fashion)! They didn't know that having an illness was BAD!!!" Things
Like. Tuberculosis was lethal. And they knew that. Almost everyone either knew someone who had it or knew someone who knew someone. It's all very well to have your hero or heroine poetically waste away from it in a novel- people forget that beautiful artistic MALE characters were frequently given TB as well -but I assure you, they were quite aware of the reality of the situation. And the reality is far less ~ tragically beautiful~ and far more full of bloody mucus
So no, nobody was trying to intentionally look like they had consumption – or even, in some versions of this myth that I've heard, intentionally GETTING consumption for beauty purposes. They were just following beauty standards that had existed for a very long time at that point, and consumption developed a place in fiction because of it
