best, In Rome, and Venice, and the Amalfi Coast, I never had a problem in shorts or short sleves........in any church at all or museums, etc, although I wore very thin pants in St. Peters.
I would never wear sandals anywhere in Europe, just not my thing.
It is ridiculous to set a detective story in New York City. New York City is itself a detective story...
