The key is the women’s outfit apron and worn with boots
I looked tons of Traditional clothing. It is not traditional German Dirndls, Greek, Turkish, Albanian, Italian, Russian
The closest thing I found was Polish: black boots, aprons, long sleeves, separate color bodices.
Polish folk dress does not seem to have white tights, Maybe this has a lot of artistic license in it.
