Alexandre Arnault
Then there's 30-year-old Alexandre, eldest son from Bernard's second marriage to Hélène Mercier.
For his own high-profile wedding to Géraldine Guyot in 2021, which was attended by the likes of Jay-Z and Beyoncé, the scion had plenty of access to the ultimate in "something blue" - after all, he's the executive vice president of Tiffany & Co.
And before that? He served as the chief executive of Rimowa. Not bad postings from dad.
