This is Giovanni Barberis Organista, tailor to the Vitale Barberis Canonico family. The two families are only distantly related (the last two names are both surnames, indicating a split at some point). More importantly, Giovanni’s family have made suits for the VBC family for three generations.
Today, Giovanni is semi-retired, making around three suits a week with his wife for help. He trained in Turin, though he says he “should have gone to Savile Row 60 years ago to train with the best, as they were then”.
