Maxima Zorreguieta, Princess of the Netherlands (*1971)
Maxima Zorreguieta wore a tiara for the first time in August 2001 at the Norwegian royal wedding. Although she was not a princess she had her 2nd appearence with tiara in October 2001 when the Spanish king and queen visited the Netherlands..
October 2001: this was already her 2nd tiara (although she was still not a princess! I like this idea!)
On her wedding day in February 2002 she wore her 3rd tiara
