Princess Charlene made her debut with black hair and a rainbow gown at the Monaco Grand Prix

Princess Charlene is one of the few royal women to sport a pixie cut and today, she’s debuting a darker shade of brown.

Pictured singing the National Anthem just minutes before the start of the Grand Prix race, the 45-year-old stood proud in a simple a-line gown.

The navy blue tone complemented her new locks, which appear much darker than the silver-blond look she styled for King Charles’s Coronation.

For the summer event, Charlene opted for a sleeveless, floor-length number that featured colorful strands down the center of the pleated gown.

She also donned glamorous sunglasses to complete the simple yet eye-catching ensemble.

The mother of two is the epitome of grace as she watches the thrilling races of her home country.

While Charlene’s long chiffon gown was relatively shapeless, the fabric perfectly hugged her slender figure — especially her small waist, long legs, and strong arms.

An insert of colorful stripes down the center of the garment elongated her tall figure while adding a bright contrast to her fair skin and dark hair.

In keeping with her slightly edgy yet chic style, the Princess wears dark nail polish and cobalt blue heels in a royal palace design.

Charlene styled her hair in a deep side part with face-framing fringe swept to one side of her face.

Highlighting her sharp bone structure, the royal channeled Kate Middleton’s soft makeup look with bronze contours and luscious pink lips.

Her eyes appear to be sprinkled with shimmering shadows and her cheeks are flushed with a light pink blush to match her defined lips.

For an added touch of glamour, the Princess, who was born in Zimbabwe, wore delicate silver studded earrings. This appears to be the only accessory styled for the event.

While the dress looks like a new look for the Princess of Monaco, Charlene’s heels look similar to her previous style.

The suede shoe features a raised point to the forefoot and a garden ombre, perspex heel with a large square base.

A lover of designer wear, the stiletto is none other than Christian Dior and sells for £332.39 at the Vestiaire Collective.
