Here are a few pictures I've gathered for costume ideas. Depending on who is cast as what, some children will be playing adults, and the others will be playing children.
Women's dresses
The fashion for the young girls seemed to be drop waist dresses that went to the knee.
For the young boys nickerbottoms were popular. A collared shirt with suspenders will work fine instead of a coat.
The men wore suits with eaither a cap, or flat top hat.
Big extravagant hats were very popular among the women. They'll definitely be needed for who ever is cast in among the "pick-a-little talk-a-little" ladies.
More hats and dress ideas for women.
