How Princess Charlene of Monaco's style has evolved, from her days as an Olympic athlete to a European princess

She was photographed in South Africa wearing a laid-back look that consisted of gray sweatpants, a navy-blue windbreaker, and Nike sneakers.

For the photo shoot, Charlene wore a sporty red tank top, white flared jeans, and a sailor hat. In keeping with the easygoing, nautical aesthetic of the shoot, she opted to go barefoot.

For the big night, she wore a black floor-length gown that was elegant and a world away from Charlene's previous ensembles.

It featured a sweetheart neckline and a long skirt with a lace-lined slit that reached her knees.

She paired the gown with silver drop earrings and a matching clutch.

For her first appearance at Monaco's annual Red Cross Ball, Charlene wore a sparkly, semi-sheer, backless ball gown that she borrowed from a friend, she told Tatler in 2010.

Reflecting on the look, Charlene wasn't exactly fond of her choice. "I looked like a Christmas tree," she said.

"I was used to living in a swimsuit and totally clueless about fashion. The day of the ball, I had been playing volleyball all day on the beach and didn't think about getting ready until late in the afternoon," Charlene added.

In a separate interview with Vogue before her 2011 wedding, Charlene remembered the outfit as one of her least favorites.

"Finding my fashion feet has certainly been the biggest challenge," she said. "I realize that my debut into Monaco society should have been better executed!"

She wore the casual ensemble during a visit to Richards Bay, South Africa, to teach swimming lessons to children.

For the event, she wore a black, strapless bustier top over asymmetric suit pants that featured a slit on the left leg. She accessorized with a sheer black scarf and a black clutch.

Charlene's sleeveless dress featured a daring neckline and colorful jewels. A matching biker glove and a small black clutch completed the ensemble.

For the official photographs that accompanied the big news, Charlene wore a colorful, floor-length dress.

The flowy blue-and-green gown was designed by Akris. It was backless and featured an elegant halter neck.

The official portraits also showed her sparkling engagement ring, which featured a three-carat, pear-cut diamond surrounded by smaller round jewels.

The ensemble, made of a blazer and palazzo pants, was both regal and reflective of Charlene's sporty aesthetic.

"It's feminine and keeps with tradition yet has a little twist that reflects my personal style," Charlene told Vogue. "I thought it was a nice change to go for trousers instead of a skirt, especially since I'm an athlete and have always kept my clothes clean and simple."

The designer told Vogue that the off-the-shoulder gown — which was made of Duchesse silk and silk organza — was covered in 40,000 Swarovski crystals, 30,000 gold stones, and 20,000 mother-of-pearl teardrops.

The look was completed with an intricate silk-tulle veil that took around 100 hours to embroider.

For the occasion, Charlene wore a sleeveless, ivory Akris gown that was partially sheer at the top and featured a cutout at the back.

The sleeveless Ralph Lauren gown featured a ruffled halter neck and a small train. She paired it with a simple gold bracelet.

The princess paired the unique jacket with a black turtleneck, black leggings, and leather knee-length boots.

Charlene's shimmery, strapless pantsuit — which was designed by Versace — featured semi-sheer, palazzo-style pants.

She wore it with silver sandals, a metallic clutch, and diamond earrings.

Charlene wore the bold dress with a black leather biker jacket and silver stilettos.

She kept the top buttons of her white shirt open and wore her suit jacket casually over her shoulders.

Charlene's hairstyle drew mixed reactions after the annual Christmas event in Monaco. Nevertheless, she told the French magazine Point de Vue that she didn't care for anyone else's opinion.

"This haircut was my decision," she said. "It seems that it has provoked all kinds of comments. But it turns out that I wanted it for a long time. The style pleases me. That's all."

The unique jumpsuit was designed by Terrence Bray. It featured a wide neckline, puffed bell sleeves, and pants so long they covered her feet.

Charlene's eye-catching white coat was designed by one of her go-to brands, Akris.

The princess paired it with a black turtleneck, leather gloves, and a wide-brimmed hat made by British hatmaker Stephen Jones.

The festive dress was designed by DidierAngelo. Charlene coordinated the gown with her lipstick, jewelry, heels, and nail color, all in similar shades of scarlet red.

She attended a gala dinner at the F1 Monaco Grand Prix wearing a custom Louis Vuitton dress.

The vibrant red piece had a straight floor-length skirt, off-the-shoulder long sleeves, and a silver, sequined collar that extended from her shoulders to the gown's neckline.

She wore the outfit with a thick diamond bracelet and matching earrings.

Her Dolce & Gabbana gown was truly unique with two distinct layers. It featured a strapless velvet gown beneath a layer of green lace.

The latter had a single puffed sleeve and a velvet belt that matched her dress.

Charlene completed the look with black pumps and emerald earrings.

She attended the 2026 Ceremony of the Sainte-Devote in a navy-blue look that comprised a thick winter coat, a matching scarf, leather gloves, pumps, and a headband.

She also carried a small purse and wore a gold brooch on the bodice of her jacket.

Charlene was photographed arriving at the event in a black Jenny Packham gown, one of Kate Middleton's favorite designers.

The elegant design featured a floor-length skirt, a strapless neckline, and a beaded mesh overlay that covered her shoulders and added short sleeves to the look.
