We went to the Vatican before Frankie and you did not go in unless your clothes were modest and respectful. Ladies knees and shoulders covered no shorts for men. Another standard gone l guess thanks to the anti Pope.
In fairness, the circus has been coming to the Vatican for many years now. The costumed performers do meet the pope, this is normal. Would I like more modest costumes? Of course. Keep in mind that they are in the audience hall and not inside St Peter’s.
