When I was in Italy decades ago, one never visited a Catholic Church without your body being covered. Short sleeves were ok, but you had to wear long pants and no bare shoulders or cleavage. The churches there also still preferred a head covering, although by then, they weren't going to throw out the tourists who didn't have one. Not sure what the rules are now.
But then again, what should we expect from those two classless and clueless grifters?
Oh, and by the way, are we taxpayers paying for this trip?
