I like to listen to Catholic Radio, and you get a lot of random exclamations and bemoanings regarding pervasive immodest dress. It's also tied up with respectfulness - or lack thereof - to occasion (church), self, and others. And they get on the case of religious people too, who abandon their orders' 9th century habits.
I find it a little irritating, because I see in it, like shevia, the same sort of vanity and focus on the superficial and objectification. You get more coverage instead of less, but it's the same difference as far as I can see.
There's also a lot of unrecognised confusion on the part of the commentators, IMO, re. what is immodest and what are unshared cultural norms. Same church does not mean same culture.
And with regard to the habit - frankly, nuns and monks wore what was the norm of their day. We have central heating now, you know. Don't get me wrong, I support the habit, but I always want to yell "let's not get carried away!" about why.
Anyways, you really don't want to hear what these people think about yoga! Ohmigosh, I feel they're really super silly. It reminds me of this astute lady's observations I just heard about on the radio. She wrote a book about being Nigerian and coming to the U.S. and learning to be black and people talking to her about watermelon and her not understanding what's wrong with saying you like watermelon.
I will thrown in here at the end that I think they're right in one respect: People say something about themselves with the way they dress, and not many employers have work for hoochie mamas.
