I have noticed, during the course of the many Papal Masses that I have seen on EWTN since the election of Pope Benedict XVI, that I rarely see a pant’s leg on the Holy Father. I was noticing his red shoes, but, not a pant’s leg. Oddly enough, I also noticed the same thing when a prelate friend of mine celebrates Mass while wearing his cassock beneath his vestments. I will notice the magenta socks, but, there is not a pant’s leg.
I asked him about that and he told me that (not sure if he was joking), but, that they make clerical knickers, kind of like what was worn back in the late 18th century. But, I’m not sure.
