The bride's witness was her new sister-in-law, Princess Alexandra of Luxembourg, while Claire's brother, Felix, fulfilled the witness duties for Prince Félix.
The new princess wore an "off-white ensemble made from wool crepe and lace details in the top, with capped sleeves and nude heels." The peplum dress was designed by Dutch designer Jan Taminiau. Claire carried as bouquet of Avalanche Platinum roses and white hortensias, according to the Wort.
Prince Felix was dressed in a "classic dark suit with a orange tie," honoring the house of Nassau.
After the wedding and reception, the couple drove off in a 1958 BMW Isetta.
The couple will be married in a Roman Catholic ceremony in the south of France on Saturday. 370 guests are expected to attend the wedding and reception.
