dmedicinus welcome to fff.
My family lived on a farm in Minnesota during my early years, it was around WW2 time, I was too young to go to war but I clearly remember how things were.
In the area where we lived all of the Ladies of all ages wore floor length dresses that did not show any part of the ladies foot, they were that long. Shoulders, arms and heads were always covered. We attended a Swedish Covenant Church that had Baptist like beliefs.
Then my parents became involved in what we would now call home missions. They traveled the country from North to South building interest of people to start churches in small towns, form Minnesota to South Texas.
I remember how my mom was amazed at the clothing the ladies wore in the larger towns we would visit.
When mom would see a lady wearing a dress that showed her ankles she would remark under her breath, "look at that hussy, make sure you stay away from girls that dress like that. Well over the years mom changed, her dresses got shorter and shorter, they never did make it up to her knees but she did show her ankles and she sure wasn't a hussy.
My point is that what is immodest in one generation is no longer considered immodest in the next.
I have heard preaching against pianos in the church house because they have them down at the saloon and they use them to play dance music for the dancing girls. Pianos were thought to be the devils music boxes.
Many of the hymns we sing in church today used worldly bar tunes. That's a study all it's own.
In the 40s the telephone was just starting to be installed in some houses, the old crank kind. Again there was preaching against telephones and all the manner of evil they may provoke.
These issues are certainly of a relative nature so it is not possible to be too dogmatic on things such as dress.
What is modest to one is immodest to another.
There are extremes, on one side we have total nudity, on the other ladies wear burkas with screens so their eyes cannot be seen.
