Sydney Sweeney and Heidi Klum led the sheer fashion trend on 2025 red carpets

Sydney Sweeney stepped out at Variety's Power of Women event in Los Angeles wearing a shimmering silver gown.

The "Euphoria" star's floor-length dress featured sheer fabric with soft draping at the waist, subtly revealing her figure beneath the metallic sheen.

The supermodel arrived in an oversized, menswear-inspired double-breasted wool coat that skimmed the floor, leaning into Vetements' signature approach to deconstructed tailoring.

Naomi Watts left little to the imagination at the red carpet premiere of "All's Fair" at Maison de La Chimie in Paris Oct. 21, 2025.

Watts wore a black lace long-sleeve turtleneck top featuring a dramatic cutout running from the neckline to the waist. She paired the sheer piece with a high-waisted midi skirt with a three-layer hem from the Valentino spring 2025 couture collection.

She added a tailored finish with a suit coat draped over her shoulders, detailed with a contrasting white lapel and bow accent.

The look was a nod to the night's "Superfine: Tailoring Black Style" theme through its sculpted structure and refined detailing.

Jenner kept her neck bare and accessorized with statement earrings, a three-ring ear cuff, long sheer black gloves and a large stone ring. She wore her hair pulled back into a slicked-back bun.

Berry wore a sheer striped LaQuan Smith gown featuring a plunging neckline and trailing circle train.

She paired the gown with a cropped black blazer and a black veil fascinator, adding a diamond Cartier statement necklace and matching drop earrings. Berry wore her hair in a neat bun and completed the look with a dark smoky eye and a matte nude lip.

In her caption, Berry thanked LaQuan Smith for designing a gown that "rose to meet the depth and strength of this year's theme."

Jenna Ortega stepped onto the red carpet at the 2025 Emmy Awards wearing an ornate, jewel-encrusted Givenchy look that quickly became one of the night's most talked-about outfits.

The jeweled top was paired with a sleek black skirt featuring a thigh-high slit, keeping the focus on the intricate gemstones across her torso.

The "Wednesday" star trusted the precise placement of the oversized gems, according to her stylist Enrique Melendez.

"It was our first time doing something this kind of revealing at all."

The flowy design featured delicate embroidered detailing, a plunging neckline and soft ruffled trim along the bodice and hem.

The "Don't Worry Darling" director skipped a top entirely, opting for coordinating white briefs beneath the see-through gown. She accessorized with a gold seashell-shaped clutch and a silver pendant necklace, wearing her hair in loose waves with smoky eye makeup and a nude lip.

Her gown reflected a growing 2025 trend of sheer fabrics and intentionally visible undergarments on the red carpet.

The high-neck, long-sleeve design featured strong shoulder pads and thousands of shimmering embellishments that caught the light from every angle.

She paired the look with pointed black heels and diamond drop earrings, styling her hair in a high ponytail and finishing the ensemble with bronzy glam.

Dakota Johnson attended the Kering Foundation's 2025 Caring for Women Dinner wearing a daring sheer lace gown from Gucci.

Her long-sleeve black dress featured intricate floral lace from the high neckline down to the sweeping train, revealing a black bra and matching underwear beneath the embroidered design.

The "Fifty Shades of Grey" star styled the look with an elegant updo and soft-parted bangs, adding emerald drop earrings. She completed the ensemble with dark eye makeup that complemented her light blue eyes.

The sheer base was covered in intricate beadwork forming floral and paisley motifs across the length of the dress.

The figure-hugging design featured a dramatically low back accented by delicate crystal straps. The "Barbie" star styled her hair in a sleek updo and kept accessories minimal.

The figure-hugging look featured a nude-toned base layered with shimmering beaded strands across the dress. She styled the sheer number with a satin black coat draped over her shoulders.

Simpson completed the ensemble with a sparkling choker necklace, silver platform heels and a coordinating black-and-silver clutch. The "Irresistible" singer wore her hair in loose waves and leaned into glamorous makeup.

The model wore a black sheer turtleneck top paired with a black mini skirt, layering the outfit with a fitted black blazer worn open over the see-through fabric.

She finished the look with sheer black tights and pointed heels, styling her hair in voluminous layers and opting for classic makeup.

The sheer black look featured delicate lace throughout the fabric and a deep plunging neckline. She styled the jumpsuit with emerald statement earrings, natural makeup and loose waves.

Moore later marked the moment on Instagram, writing, "Thank you @gucci for this birthday suit
