Like today, ladies fashion and hair have varied and changed with the times. The 1870’s had it own specific looks. Some sites that highlights these looks are:

Lime most things in C.O.G. Chronicles, I am happy to adjust and change things to suit my purposes. That is the chief advantage of making and alternate reality. However, I still like to see where it comes from initially so that I can make those changes purposefully, not accidentally.
