Princess Charlene looked stunning as she rocked a chic daytime look aboard a boat for an event held by her charity Princess Charlene of Monaco Foundation.
The Zimbabwean-born royal, 46, was seen wearing a pair of bright white skinny jeans which she paired with a fitted white T-shirt.
The star of the show was her ultra-cool Louis Vuitton anorak which came in a navy hue, was covered in the iconic LV monogram, and featured a tapered waistline thanks to a drawstring. The royal looked effortlessly put together with a simple makeup look featuring a bright pink lip and her cropped blonde locks look sleek tucked behind her ears.
The Operation Poseidon charity event took place in collaboration with the Automobile Club of Monaco in the presence of the Princess' rarely-seen brother, Gareth Wittstock, who is the secretary general of her foundation.
The former Olympic swimmer's foundation seeks to save lives by fighting against drowning and educating children through the value of sport.
A totally different look for the Princess
Princess Charlene rocked a contrasting look when she stepped out in support of her husband, Prince Albert, who was honoured with the Commander of Agricultural Merit by French President Emmanual Macron.
The royal wowed in a pale pink and grey checked double-breasted suit jacket and matching wide-leg trousers which had her looking like a perfect workwear Barbie.
Underneath the blazer jacket, which was styled buttoned-up, Charlene wore a crisp white shirt and to complete her look, rocked a pair of neutral heels.
Also in attendance were the royal couple's twin children, Prince Jacques and Princess Gabriella, nine. The male heir wore a smart suit to match his father, while Princess Charlene's mini-me, Gabriella, looked angelic in a coat layered over a balletic tulle dress.
Princess Charlene in skinny jeans
The mother-of-two proved her sartorial prowess when she once again wore skinny jeans but in a dark blue wash.
Charlene was spotted at the the Sainte Devote Rugby Tournament in April looking the picture of chic in a cream pinstriped blazer and a tan Hermes belt to match her Manolo Blahnik 'Homeraso' pumps.
She styled her chic white skinny jeans with a navy double-breasted blazer, striped shirt, and navy flats when she joined Prince Albert and Prince Jacques at the Monte-Carlo Masters.
