Princess Charlene of Monaco looked stunning in a black wetsuit as she taught children how to swim at the launch of her charitable foundation at the Annenberg Community Beach House in Santa Monica, California, on Wednesday. The former Olympic swimmer from South Africa jumped into the pool to teach water safety skills to kids. Although it was an official engagement, the 38-year-old princess looked stylish in the one-piece suit.

The wife of Prince Albert II of Monaco showed off her toned body, slender arms and legs in the wetsuit. The mother of twins accessorized with a delicate bracelet and a necklace with a cross pendant. Charlene flaunted her blond pixie cut and looked flawless in her makeup.

Charlene put on black eyeliner and mascara and a hint of pink lipstick. She later donned an orange dress and spoke about how she spent years teaching underprivileged children basic water safety techniques around aquatic environments. Her crepe below-the-knee dress featured a V-neckline, cap sleeves and a pencil skirt.

“Around the globe, thousands of innocent lives are tragically lost to drowning every year. I am here to share with you how many lives we are saving — and how many we can save, simply by training the trainers and by focusing on one person, one family, and one community,” Charlene reportedly said.

Santa Monica’s Mayor Tony Vazquez presented the stylish royal with a Mayoral Proclamation to mark the occasion. She was joined by former Olympic diver Greg Louganis, Olympic swimmer Dara Torres and champion surfer Nic Lamb. They celebrated the launch of the U.S. chapter of the Princess Charlene of Monaco Foundation with more than 40 children in the age group of 8-13, from the Boys & Girls Clubs Saint Anne School branch.

On Thursday, the prestigious Blue Ribbon of the Music Center in Los Angeles honored Charlene with a special lunch and presented her with a commemorative award in appreciation for her work in drowning prevention. The foundation shared the pictures from the event on its Facebook page.
