Needed in America - Respect for God
If you're not wearing respectful clothes, please don't enter.
"Si prega di usare un abbigliamento adeguato alla casa di Dio. Pertanto si invita a non entrare in pantaloni corti, in minigonna, in canottiera, con la schiena scoperta o con abbigliamento troppo scollato. Grazie!"
Roughly translated: "Please use appropriate clothing to the house of God. Please don't enter wearing shorts, mini-skirts, in a singlet, or with backless or low-cut clothing. Thank you!"
Jeff's tranlsation: Wear modest and respectful clothes, for goodness' sake! God is here!
