Now that I have discovered this whole issue on the ultratrad side of the spectrum, I see "immodesty" everywhere. Before I knew that people cared, I would have never been bothered by say, a woman in a one-piece bathing suit, or a tank-top and jogging shorts, or a ballet outfit, or, God forbid, pants.
So now all these things that were once neutral in my sight and mind are suddenly "sexualized" because I am constantly wondering "well, is that really modest enough ...
I also received this from a priest of my acquaintance, which serves as an effective response:
Even those who vigorously oppose relativISM have become accustomed appropriately to relativize certain propositions, such as when a hemline is "modest" or not. I know a family in which even the WOMEN will not join a gym, because of the clothing of OTHER women. Ultimately, if one is chaste, one will not be much concerned with what other people wear. Many people think that the virtue of chastity is that virtue which enables us to obsess about, and criticize, what other people are wearing and how much skin they are showing.
