I've been working on gathering CC for this, though right now I've just focused primarily on the first couple of generations. It's a struggle for sure, and most of my focus has been on clothing! I think what's making me struggle is just finding things that suit the specific era; and I'm no history major, lol. Like, fashion from 1890-1910 seems fairly similar, which I guess can be a good thing. I find it a little frustrating because I want to be able to differentiate better x_x I wish I could link what I have found for others.
Sims Resource is always my go-to, but I was very disappointed in the lack of options there. So for the most part I've been using historicalsimslife.blogspot. Her CC is gorgeous, though tailored more for the History challenge. She also has a few mesh links to a other relevant pieces!
