Dress code
Women (and men) visiting St. Peter's Basilica, the Sistine Chapel or the Vatican Museums in Vatican City are expected to wear appropriate attire. Low cut or sleeveless clothing, shorts, miniskirts and hats (for men, indoors) are not allowed. Women may or may not wear the traditional "black hat or veil". Dress code for Papal audiences is somewhat more formal. Women cannot wear clothing that does not cover the shoulders and the knees.
