I've been to Italy many times and the old adage that they won't let you in to religious sites wearing shorts or skirts above the knees no longer really applies.
Now I hear that Spain still holds dear to this policy. Is it true?
I would hate to go all that way and not be allowed admitance but I also hope to stay cool in 95 degree temps.
What do you advise tastefully, but temperature sensitive travelers to wear?
