During the world premiere of the sequel hosted in London on Thursday, stars like Zendaya, Timothée Chalamet, and Florence Pugh arrived wearing various metallic garments that matched the film's futuristic aesthetic.
And naturally, a couple of their looks were very bold.
Here's what those celebrities and others wore, ranked from least to most daring.

After making a daring entrance on the sandy carpet, the "Dune: Part Two" star changed into a modern Mugler gown that was far more simple.
It was crafted from black, form-fitting fabric and featured thin straps above its sweetheart neckline.
She wore the elegant dress with vintage Bulgari jewels, including a diamond-encrusted emerald ring and sparkling earrings.
Greta Gerwig made an appearance in diamond jewels and a green gown.Greta Gerwig attends the "Dune: Part Two" premiere in London, England.

Her Jil Sander dress, which retails for $4,300, featured a ribbed bodice with long sleeves and a wide skirt embellished with pleats.
Gerwig completed the look with pointed white boots, glowing makeup, and a diamond necklace that wrapped around her gown's neckline.
Though the outfit wasn't daring, it was certainly expensive.

Designed by Fendi, the gown had a high neckline, a straight skirt, and a cape-style piece of fabric that extended over one shoulder to reach the floor.
A strip of silver sequins on the dress was shaped to match its silhouette and made the look more fun.
Still, the outfit overall was far from the boldest one seen on the "Dune: Part Two" red carpet.
Austin Butler opted for a classic menswear look with a small twist.Austin Butler attends the "Dune: Part Two" premiere in London, England.

Most of his Gucci outfit was simple, featuring black trousers, dress shoes, and a white tank top embroidered with the fashion house's name along its low neckline.
But his jacket stood out a little bit more.
Not only did it have a bit of padding across the shoulders, but the piece also reached the floor in the style of a dramatic cape.
Léa Seydoux looked like royalty in a dress that was equally glamorous and bold.Léa Seydoux attends the "Dune: Part Two" premiere in London, England.

Her sleeveless silver dress was custom-made by Louis Vuitton.
It had thin straps with cape-style sleeves attached, a V-shape neckline, and a form-fitting bodice decorated with crystals.
Its skirt was also bold, featuring a short layer beneath a longer one that almost reached the floor.

Haider Ackermann designed Chalamet's outfit, which included a black blouse over a white undershirt and silver pants with knee patches and a statement zipper.
He completed the bold outfit with black boots and a thick diamond necklace.
Florence Pugh looked like she stepped off the runway in her sparkling ensemble.Florence Pugh attends the "Dune: Part Two" premiere in London, England.

Valentino custom-made the actor's gown, which hugged her body from top to bottom and was covered in burgundy sequins.
The daring look also featured a backless bodice, a short train, a hood that wrapped around her head, and a deep neckline that plunged to her waist.
Pugh completed the outfit with silver bangles and long earrings.
Anya Taylor-Joy was striking in an all-white outfit.Anya Taylor-Joy attends the "Dune: Part Two" premiere in London, England.

The actor arrived wearing a custom look made by Christian Dior.
Its dress portion had a sleeveless top with a wide V-shaped neckline and a long pleated skirt that nearly reached the floor.
But what really stole the show was the gown's matching veil, which covered most of Taylor-Joy's head and draped over her body to make the daring ensemble more elegant.

Styled by Law Roach, Zendaya wore a silver suit of armor created by Thierry Mugler in 1995 — one year before she was born.
The metal outfit had see-through spots across the thighs, backside, waist, arms, and chest.
She wore it with silver pumps and diamond jewelry around its high neckline.
