Did you notice the "bathing shoes"? YES, they DID wear special rubber shoes into the water!
I remember in the 1930s movie "Lost Horizon," there's a distant shot of the female star swimming nude in a pond. Pretty daring for those days. (I forget her name; she later played the wife on the TV show "Father Knows Best" - Jane Wyatt? Wyman?).
Why yes, that swimsuit IS very nobby!
We have a cute one in one of our shows that is SILK (v. unusual) and has a matching parasol and shoes. I bet it had a matching hat too, but that didn't make it through the years.
Note that the advertisement brags that the material does NOT cling to the figure! My how things have changed!
Thanks again for a smile!
