On Wednesday, Princess Charlene attended the Opération Poséidon charity event ahead of the Monaco Grand Prix. Pierre Frolla, quadruple freediving world record holder, dived to collect the checkered flag of the 81st Monaco Formula 1 Grand Prix. The flag will be signed by the Princely Couple and the F1 drivers before being auctioned for the benefit of the actions of the Princess Charlene of Monaco Foundation.

Princess Charlene wore a Louis Vuitton jacket with white jeans and her Louis Vuitton sneakers.
