St Padre Pio was also a Priest. He died in 1968. St Padre Pio had a lot to say on modesty of dress for both genders.
Quote from one of Padre Pio’s letters: "There are, moreover, three virtues which perfect the devout person with regard to control of his own senses. These are: modesty, continence and chastity. By the virtue of modesty the devout person governs all his exterior acts. With good reason, then, does St. Paul recommend this virtue to all and declare how necessary it is and as if this were not enough he considers that this virtue should be obvious to all. By continence the soul exercises restraint over all the senses: sight, touch, taste, smell and hearing. By chastity, a virtue which ennobles our nature and makes it similar to that of the Angels, we suppress our sensuality and detach it from forbidden pleasures.
This is the magnificent picture of Christian perfection. Happy the one who possesses all these fine virtues, all of them fruits of the Holy Spirit who dwells within him. Such a soul has nothing to fear and will shine in the world as the sun in the heavens."
"Padre Pio wouldn’t tolerate low-necked dresses or short, tight skirts, and he forbade his spiritual daughters to wear transparent stockings. Each year his severity increased. He stubbornly dismissed them from his confessional, even before they set foot inside, if he judged them to be improperly dressed. On some mornings he drove away one after another, until he ended up hearing very few confessions. His brothers observed these drastic purges with a certain uneasiness and decided to fasten a sign on the church door; "
“By Padre Pio’s explicit wish, women must enter the confessional wearing skirts AT LEAST 8 INCHES BELOW THE KNEE. IT IS FORBIDDEN TO BORROW LONGER DRESSES IN CHURCH AND TO WEAR THEM TO CONFESSION”
And for men:
The Church is the house of God.
It is forbidden for men to enter with bare arms or in shorts. It is forbidden for women to enter in trousers, without a veil on their head, in short clothing, low necklines, sleeveless or immodest dresses."
( 8 inches below the knee would be ankle length for many☺. Women had started borrowing dresses for confession. Padre Pio always knew. )
