I want to know the answer to the following question:
What type of clothing did Paul VI enact reform on?
All the background I'm provided with is that "The age limit of eighty years imposed by the Pope, a numerical increase of Cardinals by almost 100%, and a reform of the regal vestments of the "Princes of the Church" further contributed to a service-oriented perception of Cardinals under his pontificate.". Is that enough to answer the question?
Answer: yes
