We don't have specific clothes for potentially getting dirty, I just let the girls do what they want to do and hope the stains come out. We got some hand me downs and a few of the things are pretty well loved or not my style, my mom said to keep for play clothes. So I may do that with a few things if I know my kids want to go dig in the mud or something. We don't spend too much on any one item anyway so it's not a huge deal to me if things get used!
