It's definitely wedding season for the royal family of Monaco. This summer, Grace Kelly's granddaughter, Charlotte Casiraghi, tied the knot not once, but twice in France. This past weekend, it was her cousin's turn. Louis Ducruet, the son of Princess Stéphanie, and grandson of Grace Kelly and Prince Rainier, said "I do" to his college sweetheart, Marie Chevallier, in, yet again, two separate ceremonies. And though the 26-year-old is currently 15th in line to the throne, their celebration was certainly fit for a king and queen.

On Friday, the couple officially wed in a civil ceremony, a private affair reserved for family (including their dog) in the Prince's Palace. Ever the modern bride, Chevallier wore a jumpsuit designed by Spanish label Rosa Clara.

The festivities continued on Saturday with a church ceremony held at the Cathedral of Our Lady Immaculate, the same place Ducruet's grandparents tied the knot in 1956. After arriving in a vintage Rolls-Royce adorned with flowers, the bride walked down the aisle in a gown designed by her sister-in-law, Pauline Ducruet, in collaboration with Atelier Boisanger. The evening finished off with a reception at Monte Carlo Bay Hotel, with the who's who of royals in attendance, including Monaco's current monarch, Prince Albert.
