Within certain very broad parameters, modesty is culturally conditioned. The virtue of modesty is an absolute, but
how it is practiced, differs with time, place, circumstances, and even possibly the individuals involved.
The Pius XI standards were for one time and place. Our culture, for good or for ill, has morphed such that bifurcated garments (that’s Latin for “pants” as the term is used in the American lexicon) on women, above-the-knee shorts, and,
in and of themselves — there are exceptions — two-piece women’s bathing suits, are no longer considered “immodest” by any but the most severely orthodox/conservative/traditionalist/whatever Catholics. Ditto for short sleeves and necklines on women that come more than two fingers’-width below the
[EDITED TO ADD] collarbone. And as far as Padre Pio’s severe (and I do mean severe) restrictions on women’s fashion when they approached him for confession, he’s not around anymore to ask him to elaborate, and he made those standards stricter over time — surely “modest” didn’t become “immodest” somewhere down the road just on Padre Pio’s say-so. No disrespect intended, just stating the fact.
I am no fan of “modesty creep” or “fashion creep”, i.e., pushing the boundaries just a little at a time, the end result being once-patently-immodest fashions becoming modest “because everybody’s used to it by now”, but again, modesty standards do change over time, and in different places and cultures.
St Gianna Beretta Molla wore short sleeved tops and also pants- there are pictures of her on the web showing that she did. And she died before Vatican II. There are plenty of newly beatified women that wore both, and worked outside the home. None of that is sinful, and the Pope Pius Xl gave his opinion, not a declaration Ex Cathedra. Just like Pope Francis has opinions… [emphasis mine - HSD]

so glad you used that example!
