Mathilde of Belgium arrived with her close friend Argentine-born Maxima, the wife of Willem-Alexander, the heir to the Dutch throne.
Both royals lived up to their reputations as elegant dressers, with the Belgian crown princess in a bold black and white creation that was slashed to the thigh, revealing her shapely figure, and the Dutch royal in a blue and gold sari-inspired ensemble, accessorised with turquoise jewellery.
Is it me or Prince Philippe is stunned by his wife? So sweet!
