In our case, Methodist.
The first time we went to the Vatican, we had heard about the rules. I tell ya, you'd hate to wait in the summertime heat for hours as we did and then be turned away.
The rules from Wikipedia:
A dress code is enforced for entry into St. Peter's Basilica. The code is based upon what is considered "modest" and "appropriate" dress for visiting a Catholic church, and tourists and visitors are reminded that, although St. Peter's is an architectural and artistic monument, it is first a place of worship and prayer. The dress code forbids:
- hats for lay men inside the basilica
- shorts/skirts above the knees
- sleeveless shirts
- shirts exposing the navel
- shirts for women that expose cleavage
- shirts which contain profanity
- excessive jewellery
The use of mobile phones is also prohibited, as is smoking.
