Monaco’s Pierre Casiraghi, seventh in line for the throne, married Italian heiress Beatrice Borromeo on Saturday in Monaco. The bride was seen arriving to Monaco’s Grimaldi palace in a vintage white Bentley and was dressed in a pale pink Valentino gown. Borromeo paired her bespoke creation with a matching floral crown.

Italian fashion house Valentino shared a photo on Instagram – the first official one of the newlyweds to be released. The picture showed Beatrice and Pierre standing on the palace balcony, looking at each other while holding hands. The long pink-and-gold lace silk chiffon cape dress was designed by Maria Grazia Chiuri and Pierpaolo Piccioli and it is a customized version of the label's spring 2015 collection , WWD reported .

The couple said “I do” in front of 70 of their closest family and friends during a civil ceremony in the gardens of the palace. The civil ceremony was attended by the members of the royal family held in Monaco’s Pink Palace. Pierre, 28, and Beatrice, 29, were joined by around 700 guests in the Palace gardens for a carnival-themed party arranged by the groom’s uncle, Prince Albert.

The informal summer party consisted of folklore music and dance groups and the pétanque matches customary to Mediterranean summer afternoons. Guests dined on finger foods and drinks during a buffet at the reception. They were asked to follow a dress code of wearing their native regional costumes.

Pierre is the son of Princess Caroline and nephew of Prince Albert of Monaco. His new wife is a former model and journalist and belongs to an aristocratic family from Italy. Members of the Borromeo family, who had earlier hosted a wedding breakfast at Monaco’s Fairmount Hotel, were also present.

The couple will head to Borromeo’s family-owned Borromean Islands for the second round of more intimate celebrations. They will again marry in a religious ceremony on the Isola Bella, located on Lake Maggiore in northern Italy on Aug. 1, according to Italian publication Dagospia. Maggiore is Italy’s second largest lake and the longest.
