...Thomas Swift wasn't truly suggesting the Irish eat their own children in A Modest Proposal
He wasn't!?
I have no problem with sarongs - actually I like them. There were quite a few at burning man and they looked good on both genders.
Depending on how they're worn they can be completely (what's the word?) sheer? Which is more of a fashion accent and can be beautiful as well. As far as introducing fashion into a some sort of utopian naturist world? Too late - haircuts, body trimming, jewelry and body modifications put an end to that eons ago - maybe it's always been with us (back to FKK and beyond like Greece even).
I think they're way too light to be about hygiene - that doesn't make sense to me.
What does make sense are: sensitivity about one's bottom, that time of the month or just not quite ready to go all the way.
Whatever floats yer boat.
