Though the Gabriela Cadena piece appeared conservative from the front with its solid gray fabric, it was actually entirely sheer down its sides.

Only clusters of silver sparkles and see-through mesh sat atop her legs, hips, and torso. Though it worked then, the partial nudity might not fly at this year's event.

Roberto Cavalli designed Jenner's sheer black gown, which might not make it past security at Cannes today.

The long-sleeved piece, crafted from mesh, showed most of her body. She wore only high-waisted underwear beneath it.

A snake print and light glitter made the dress even more dramatic.

That year, she ditched a bra when she wore her tulle gown, which showed her chest with sheer straps that acted as a top.

Its long, tiered skirt was also see-through and voluminous, though not enough to get in the way of other people walking the red carpet.

Every inch of the actor's Peter Dundas gown was dramatic that year.

It had giant puffed sleeves, a bow that extended past her torso, and a skirt train that was so long it covered numerous steps behind her.

The gown was the definition of voluminous, especially because she needed at least two people to help her get up the stairs.

The model walked the Cannes red carpet in a black number from Đỗ Long. It was made from mesh and therefore entirely sheer.

It was also cut in a daring style. The outfit featured a backless halter top, a keyhole cutout at the chest, a thong bottom, and two thin strips of fabric in place of a skirt.

Hadid wore a plain black gown at Cannes in 2021.

However, her long-sleeved Schiaparelli dress was daring with a scooped neckline that plunged to her waist.

The model also wore a golden necklace shaped like lungs to cover her chest. Though not technically nude, wearing the same pieces at the 2025 event would be risky.

The TV star was a vibrant pop of color on the red carpet thanks to her strapless yellow dress. It was crafted from tulle in tiers of ruffles that extended into a long, thick train.

Because the skirt pieces have since been banned, there's a chance that Bodi wouldn't be able to wear the same dress to this year's event.

The model wore a simple thong beneath a sleeveless look crafted from strings of crystals, which showed her body.

To complete the look, Depina sported see-through sandals and delicate jewelry.

For one red carpet, the French model wore a black Stéphane Rolland gown. It was made with thick black fabric that draped around her head and hips in a circle and down her legs as a skirt.

What made the ensemble even more daring, though, were the layered rope necklaces she wore as a top. It was bold enough to possibly break this year's dress code.

Saint Laurent created the brown halter dress she wore last year, which was almost entirely sheer. Only her waist and hips were wrapped with extra fabric to create a more opaque look.

It might not have been Hadid's most dramatic look at the film festival, but it was one of her most see-through.

The actor and model wrote on Instagram at the time that she wanted her Cannes outfit to honor Cambodian fashion.

So she tapped designer brand De l'Elegance to create her strapless gown, matching hat, and extensive green train. It was so long, however, that similar trains might not be allowed at future Cannes festivals.

She walked the red carpet in a strapless, mauve ball gown designed by Christian Dior and a few pieces of diamond jewelry.

Her long, straight hair and neutral makeup were equally elegant.

The Dior Haute Couture dress was sleeveless with thin straps, a standard waistband, and a petal-shaped neckline.

She wore it with black sandals, heavy eye makeup, and snake-shaped Bulgari jewels.

That year, she wore a black mermaid dress designed by Gianni Versace in 1987.

It had a ruched, strapless bodice, velvet skirt, and a hoop of black fabric across her waist and hips.

Her vintage, white Gucci dress was simple with long sleeves and a straight skirt.

Though she wore no bra with the gown, she did wear a metal-encrusted pair of underwear seen through the circular cutout at her hip.

The sleeveless Saint Laurent piece was pretty simple, with only a thigh-high slit and a ruched asymmetrical neckline visible from its front.

The other side of the gown was a bit more interesting with cutouts that showed her back.

The Roberto Cavalli Couture gown had a slip that matched her skin tone and created the appearance of a see-through dress.

It was also decorated with crystals from top to bottom and had a floor-length skirt that extended into a short train.

The gown's bodice, on the other hand, was sleeveless with crisscross straps across the chest.

Her bold Elie Saab Haute Couture dress was covered in silver sequins.

It perfectly matched her diamond bracelets, earrings, metallic clutch, and sharp eye makeup.

Her Alexandre Vauthier dress was made from baby-pink satin. It was strapless with a V-shaped neckline and a wrap-style skirt that created a thigh-high slit.

Hadid wore the look with sparkling sandals and a statement Bulgari necklace.

The Jean Paul Gaultier dress had a black bra underneath a halter top made from twisted mesh. On top was another layer: a strapless white gown that sat beneath her bust.

Some of the mesh material was also attached to the back of the dress, creating a wide train that fanned out behind the model.

Hadid's red gown was designed by Roberto Cavalli.

The single-sleeve, backless design had a cutout at one hip and a thigh-high slit in the front of its skirt.

It also had a jeweled strap that wrapped around her shoulders and held the actual dress up. She wore it with red sandals, matching lipstick, and an updo hairstyle.

Her Dior Haute Couture had an asymmetrical halter top and tiers of ruffles made from semi-sheer white tulle.

In addition to the gown, Hadid donned a thick silver bracelet, diamond earrings, and a bun hairstyle.

The Saint Laurent piece had a halter neckline made from sheer mesh that revealed the model's chest. More of the fabric was wrapped in thick rows around her waist, creating an opaque panel above its sheer knee-length skirt.

Hadid wore the daring look with open-toe leather shoes and diamond-encrusted gold earrings.

She wore a red Alexandre Vauthier gown that was sleeveless, backless, and had a loose-fitting top with a plunging neckline. The bold gown also had a flowing skirt with a hip-high slit.

Speaking with Vogue in 2021, the model said she felt "embarrassed" by the look, despite it "apparently" being "a very iconic red dress moment."

"I was nervous in this dress. I look very sexual and all these things," she said. "I was still nervous about cameras and nervous about having a lot of makeup on."

Hadid also said the dress didn't match her style, and it gave people a false perception of who she is.

"That's my alter ego. That's Belinda," she joked. "I'm just so the opposite of her. She's very va-va-voom. You know, bless her. Love her. She was very nervous."

The daring design was made by Schiaparelli. The fashion house described the garment on Instagram as a "long-sleeved dress in wool crepe with a low-cut neckline."

To cover her chest, Hadid donned a large, lung-shaped necklace made from "gilded brass" and "adorned with rhinestones," according to the brand.

The pairing made for one of the most daring looks at the 2021 Cannes Film Festival.

She walked the "Affeksjonsverdi" red carpet on Wednesday in a strapless Giorgio Armani design that looked pretty and chic.

It was fitted to her body, decorated with pink rose appliqués, and completed with a plunging sweetheart neckline.

She arrived for "The Phoenician Scheme" screening on Sunday in a uniquely shaped Schiaparelli set.

The model's structured top had a beaded, off-the-shoulder neckpiece that covered her chest and a high-low peplum waistband. Her pants, on the other hand, were oversize and wide.

Though her statement blouse had potential, Consani's pants were a little too big and needed tailoring. A form-fitting skirt might have looked better with the top piece.

The actor could have looked classic with a traditional tuxedo for the red-carpet event, or he could have attempted a more daring style.

Instead, he tried to do both at the same time.

He wore a sharp Saint Laurent tux with his trousers tucked into thigh-high leather boots — a style the fashion house first revealed in its January runway show.

The shoes were distracting and felt out of place with his otherwise basic look.

For the "Die, My Love" screening, Hargitay chose an off-the-shoulder gown crafted with black satin and sparkling hot-pink fabric.

The color combination was sharp, the gown's straight silhouette fit the actor perfectly, and her elbow-length gloves made the outfit even more elegant.

His brown ensemble included a button-up shirt, a wrap blazer, straight-leg trousers, and a bow tie, all cut with raw hems.

While the rough style might have worked for a different event, it looked too casual at Cannes. His black loafers were also too harsh against the lighter outfit.

She walked the "Eddington" red carpet in a strapless, sparkling creation from the French fashion house.

Its silver top was covered in sparkles and wrapped with a black bow, while its floor-length skirt had Dior's classic Junon petals.

Portman accessorized the look perfectly with a bun hairstyle and a thick diamond necklace.

Also on the "Eddington" red carpet, Jolie wore a strapless Brunello Cucinelli design. It had a thick floor-length skirt, a fitted bodice, and all-over sparkles that highlighted its rope texture.

Though the actor looked pretty, her gown's ivory color matched her skin tone too closely and washed her out. The same dress in a pink or lilac shade could have worked better.

The Chinese actor wore the strapless dress on the "Dossier 137" red carpet. Its structured bodice was decorated with beaded appliques, and its cups were shaped with flower petals.

To accessorize the glamorous look, she added a sparkling diamond choker, matching earrings, a thick bracelet, and vibrant red lipstick.

She attended the "Mission: Impossible - The Final Reckoning" red carpet in a black Saint Laurent gown.

Though her sleeveless dress was classic, it was also overly simple. Statement jewels could have easily enhanced the look.

She also draped a dark leather jacket around her arms, which was much more casual than the rest of her outfit.

She wore a crystal-covered dress that looked like it was molded to her body with its form-fitting design.

Its strapless, snake-print bodice was corseted with a deep plunge down the middle, and its floor-length skirt was pink and embellished with countless sparkles.

The Thai actor completed her look with a large diamond necklace crafted in the shape of leaves.

Elie Saab designed the model's off-the-shoulder gown. It had a deep V-neckline, see-through stripes, and all-over sparkles in blue and purple.

Some of those details might have worked on their own. But together, especially with the gown's mermaid shape, its accents made it look more theatrical than glamorous.

Cruise attended a promotional event for "Mission: Impossible - The Final Reckoning" at Cannes.

In doing so, he became one of the best-dressed men at the festival so far this year.

He wore a fitted, textured knit polo and matching trousers with sharp pleats. The outfit was understated and vibrant on its own, while his brown dress shoes and dark sunglasses gave it an edge.

When Berry walked onto the Cannes red carpet, she wore a shapeless Jacquemus gown with a black-and-white stripe print.

She later told reporters that she'd originally planned to wear an "amazing dress" from Gaurav Gupta, but had to find a new look when Cannes announced a new dress code that prohibits voluminous gowns with long trains the day before the festival began.

Unfortunately for Berry, the bold dress she chose was so flowy and oversize that it seemed to wear her, when it should have been the other way around.

Nicolas Jebran designed her halter gown. The form-fitting piece had knotted fabric at the hip, a floor-length skirt with a short train, and a hip-high slit that revealed her sparkling pumps.

The gown was also adorned with a sparkling silver piece that covered one shoulder and was embedded with turquoise stones.

The ensemble was elegant and fit Fontana perfectly.

Saint Laurent designed her sleeveless black dress with some interesting details. Its straps crisscrossed across her back to create cutouts and a deep plunge on the side of her chest.

However, the front of the gown was overly simple. It had an asymmetrical neckline that looked mishapen, and a thigh-high slit that was cut too far to the side.

Even her massive emerald earrings from Chopard weren't enough to make the ensemble memorable.

Her Tamara Ralph gown was strapless and covered in square metallic pieces that sparkled in the light as she walked.

It also had velvet panels at the waist that gave the dress some shape and matched its glamorous train.

Not only was the dress tailored perfectly to Longoria, but the actor also accessorized strongly. She wore a statement necklace, rings, and earrings from Pasquale Bruni.

The model arrived wearing a black Armani Privé gown with all-over white polka dots. It had a strapless neckline, off-the-shoulder puffed sleeves, and a full skirt.

On its own, the dress was fun, frilly, and perfect for Cannes.

But Shayk wore her hair styled in a dramatic shape — a bun atop a strip of pin-straight hair — that distracted from her outfit.
