Their are many many unrealistic things about movies, but one of the things that is bothering me right now.
No way would the girls from “olden times” leave their hair hanging down all the time. Mother would have fixed it for them, and when they got older they would have fixed it for themselves.
They put their hair UP. Especially in olden times. Because they had work to do, and would not be able to do it, or look respectable doing it, with their long and often CURLY locks swinging around and like as not falling in a pile of cow poo.
The movies dont’ seem to have a problem with the American Indians always having their hair in braids. It’s a matter of practicality.
