Christian dads and moms used to give their kids the talk about modesty in dress, often.
When the "bikini" turned sixty the Italian press made a big deal about it and I guess I was the only one in the crowd who thought it immoral to be caught dead in public in such minuscule clothing.
A bathing suit is a bathing suit and then there are Our Lady's words at Fatima about fashions which "will be" introduced which "will offend" the Lord greatly.
Ten year old Jacinta lay dying in a hospital bed in Lisbon, Portugal in 1920 when Our Lady said to her: "Certain fashions will be introduced which will offend Our Divine Lord very much. Those who serve God ought not to follow these fashions." Then Our Lady revealed to Jacinta that "the sins that lead most souls to hell are the sins of the flesh."
Interesting to note that in all her apparitions Our Blessed Lady always appears fully covered.
Let's see what a papal encyclical says:
"One cannot sufficiently deplore the blindness of so many women of every age and station. Made foolish by a desire to please, they do not see to what degree the indecency of their clothing shocks every honest man and offends God. Most of them would formerly have blushed for such apparel as for a grave fault against Christian modesty. Now it does not suffice to exhibit themselves on public thoroughfares; they do not fear to cross the threshold of churches, to assist at the Holy Sacrifice of the Mass, and even to bear the seducing food of shameful passions to the Eucharistic Table, where one receives the Heavenly Author of Purity."
-Pope Benedict XV, Sacra Propediem , 1921.
Would be nice for more Protestant communities to be on board, too, but look at their origins - Martin Luther entered a sacrilegious marriage and King Henry entered an adulterous one.
