The former Nina Ricci staffer is now a designer of rather expensive bikinis. Her line is called Tooshies. Here is a link to an interview with the couple. The interview took place earlier this year in Moscow, where Eugenio works. His company produces a vodka, Tovaritch.
Both the bride and groom descend from Wilhelm I of Hesse.
Natascha is the daughter of HSH Prince Robin of Sayn-Wittgenstein-Berleburg and his first wife, Birgitta af Klercker. The princess was born in New York City in 1973.
Prince Robin is the third of five children of the late Gustav Albrecht Prince of Sayn-Wittgenstein-Berleburg. His elder brother, Richard, who is married to Princess Benedikte of Denmark, is the current head of the family. One sister, Madeleine, is the widow of Count Otto of Solms-Laubach, and another sister, Tatiana, is the former wife of Moritz, Landgrave of Hesse, who is a descendant of Queen Victoria as is Princess Benedikte of Denmark.
