Princess Stéphanie's Son Weds College Sweetheart — and She Wore a Jumpsuit!

This weekend marks a second royal wedding for Monaco this year, with Louis Ducruet and Marie Chevallier exchanging vows in what is being called "a private family affair."

People magazine reports that Ducruet — the son of Princess Stéphanie and Daniel Ducruet — and Chevallier were wed in a civil ceremony at the Prince's palace on Friday, and in a religious ceremony on Saturday at the Cathedral of Our Lady Immaculate, where the groom's grandparents, Grace Kelly and Prince Rainier II, wed in 1956.

The ceremonies came just a month after Louis' cousin, Charlotte Casiraghi, married Dimitri Rassam.

In what is being called a royal-wedding first, Chevallier wore a jumpsuit to her civil ceremony! The white silk crepe creation with embroidered lace and an open back was the handiwork of Barcelona's Rosa Clará. For her cathedral vows, she wore a gown designed by Louis' sister, Pauline Ducruet, a Parsons School of Design grad.

The guest lists were tiny, with just close family and friends in attendance, but the groom said he was happiest to feel close to his late grandfather by marrying in the same cathedral where he had married the former film star Grace Kelly. “I was really attached to my grandfather, and I wanted him to be here with me. At some point he will be with me during the wedding ceremony at the cathedral. That's why we chose it, and Marie supported me in this decision, even though the place is big and there's a protocol, but that's the only way for my grandfather to be with us."
