What did working-class people wear in the 1820's-1840's (pioneers)?

We’re going on a pioneer trek and I want to make a dress that is accurate. This would be made out of cotton fabric and suitable for walking a LONG way. Pioneer women would probably wear something like this when they were out working in the farm. I’ve looked it up, but all I can find is high fashion for that age. Pictures, books, websites, etc. would be fantastic. Thanks!
