On Saturday, November 7, 2026, Rosie Huntington-Whiteley, Vittoria Ceretti, and Amber Valletta were spotted arriving at the Los Angeles County Museum of Art for the 15th Annual LACMA Art+Film Gala, which was sponsored by Gucci and Audi, honoring Latvian-American visual artist Vija Celmins and Canadian filmmaker Denis Villeneuve, with a performance by Rosé from the South Korean girl group BLACKPINK.
At the 2026 LACMA Art+Film Gala, the three celebrated fashion figures commanded attention on the red carpet, radiating effortless confidence in custom black Gucci creations with striking high slits, each designed by the brand’s creative director, Demna. In today’s blog post, I’m highlighting English model Rosie Huntington-Whiteley, Italian supermodel Vittoria Ceretti, and American model and actress Amber Valletta, who each wore a high-slit Gucci look to the 15th Annual LACMA Art+Film Gala. Keep scrolling to discover how each star offered her own distinctive take on Gucci for the occasion.
Rosie Huntington-Whiteley Steals the Show in Black Custom Gucci With High Slit and Open Back
Tiffany & Co. and Saint Laurent global ambassador Rosie Huntington-Whiteley was photographed striking confident poses at the 2026 LACMA Art+Film Gala in a custom black Gucci column gown inspired by the look American model Alex Consani wore on the runway for the brand’s Spring/Summer 2027 “The Store” ready-to-wear show at Milan’s Allianz MiCo Convention Centre during Milan Fashion Week.
Her bespoke long-sleeved dress replaced the catwalk’s crew neck with a structured, sculptural high turtleneck that rose dramatically to cover the entire front while maintaining the open-back silhouette, which plunged into an exceptionally deep scoop to expose her skin and secured at the left waist with the same solitary round silver-metallic embellishment embossed with Gucci’s signature Interlocking G logo.
The dress also cascaded gracefully to the floor, embellished with rows of rich green sequins and the same ultra-high side slit, beginning at the brand’s signature round silver-metallic accent that set it apart from the bodice above. In this daring creation, Rosie Huntington-Whiteley commanded the room, her magnetic presence capturing every eye.

To finish her sultry, thigh-high-slit Gucci ensemble, “Mad Max: Fury Road” star Rosie slipped into coordinating “Donna” pumps crafted from supple black nappa leather, complete with pointed toes, stiletto heels, and Gucci’s signature Horsebit emblem in polished gold-tone metal; the design drew inspiration from the brand’s Primavera ready-to-wear collection, created by Georgian designer Demna Gvasalia.

Furthermore, she finished her event ensemble with Tiffany & Co. jewelry, including platinum and 18k yellow gold drop earrings inspired by the brand’s Bird on a Rock by Tiffany collection and adorned with green tourmalines, diamonds, and rubies, as well as oval green tourmalines totaling 12.00 carats.
Vittoria Ceretti Dazzles in High-Slit Gucci With Bold Cutouts
Meanwhile, 28-year-old Victoria’s Secret model Vittoria Ceretti made a graceful entrance at the 15th Annual LACMA Art+Film Gala, exuding sophistication in a custom Gucci floor-length gown.
The midnight-black velvet column gown boasted an exaggerated, sweeping off-the-shoulder bateau neckline that gracefully framed her collarbones, a sculpted corset bodice accentuating her hourglass figure, and a daring high slit climbing her left thigh, revealing a deliberate glimpse of skin with every confident step.

Her high-slit Gucci ensemble was completed with matching Giuseppe Zanotti “Guepiere” pumps crafted from black nylon mesh, trimmed in grosgrain and defined by elongated toes and 105 mm conical heels, plus Nikos Koulis jewelry, including drop earrings, an 18k white-gold “Look” diamond necklace, and a coordinating “Wish” ring.
Amber Valletta Captivates in a Daring Gucci Gown with a High Slit and Open Back
Lastly, Amber Valletta captivated the 15th Annual LACMA Art+Film Gala in a custom Gucci gown, reimagined in sumptuous black velvet from the beige version worn by 27-year-old American model and actress Meredith Mickelson during the brand’s Spring/Summer 2027 “The Store Show” ready-to-wear runway.
The gown maintained the original runway design’s sculptural one-shoulder silhouette, with an asymmetrical drape crossing the bodice and an open back adorned by a large, intricate interlocking “GG” motif trailing down the spine. It also kept the bold thigh-high slit, rising along the upper thigh to reveal her leg, while the train unfolded into a long, dramatic sweep across the floor rather than the shorter version.
