Talk to the suit.
Jacopo Pontormo, Portrait of a Young Man (c. 1526)
Cosimo de’ Medici spoke to a friend of his who was very rich but not very learned, and had obtained through Cosimo a mission outside of Florence, and asked Cosimo as he was leaving how he ought to behave to succeed in this mission. Cosimo replied: “Dress in rose color, and speak little.”
