For the ceremony surrounding the symbolic boat on the Quai Antoine Ier, the mother of two got changed out of her Louis Vuitton coat and into a plum asymmetric coat by Alexander McQueen.
Her coat, which was designed by the Princess of Wales' go-to designer, was teamed with her 'Ribbon 85' boots by Gianvito Rossi and a beautiful pair of rose gold hoop earrings adorned with three tiny pearls from Maison Tabbah.
Her lookalike daughter was so sweet in a black and dark green tartan coat dress for the rare occasion where she didn't match her stylish mother.

Her ensemble, featuring a popped collar, was amplified with the boxy black blazer worn over her shoulders, rule-breaking red manicure, and dripping diamond necklace.
