My impression that older women favored transparent fabric is just that—an impression. I base it on my photo collection featuring older American women, cobbled together from found snap shots, magazine and newspaper articles, and pictures from online archives. Although it is large, I cannot claim that it is representative.
But left me present some examples from one decade, the 1940s, to illustrate my claim. At top is a photo of the head of the African American division of the Home Demonstration workers in North Carolina, Dazelle Foster Lowe, in a dress with a transparent bodice. Next we see a lace maker at the Los Angeles County Fair in the 1940s with an entirely transparent dress.
Transparent arms and bodice were quite common on dresses for special occasions. Here are three of many.
Do you have any examples to add from your family photo albums?
