There are several taboos that apply to those visiting or living in Vatican City. There is no smoking allowed anywhere and the use of mobile devices is strictly prohibited. They also have a very strict dress code in place. You may not wear excessive jewelry, clothing with profanity on it, sleeveless shirts, and skirts or shorts that fall above the knee. Once inside the Basilica, men may not wear hats.
