Chase Infiniti kept the Louis Vuitton run going in Lille on Friday night, arriving at the opening ceremony of the 2026 Series Mania Festival in a custom cobalt gown that traded her recent softer red carpet silhouettes for something much bigger and more theatrical.

Infiniti’s glossy blue dress featured a wide off-the-shoulder neckline that opened into oversized folded ruffles like waves across the bust and around the tops of her arms. The neckline sat high and broad, almost like a gathered collar, before the gown narrowed through the torso. Tight vertical ruching compressed the fabric from chest to waist in narrow, packed lines, giving the middle of the dress a cinched look without any visible boning.

From the dropped waist, the skirt widened into a full ball-gown shape with dense volume through the hips and long folds to the floor. The cobalt fabric carried an almost lacquered shine that caught lighter flashes across the neckline, the ruched torso and the sweep of the skirt.

As for accessories, Infiniti paired the look with an Antoine Rinascimento choker, a trilogy ring and coordinating earrings. She wore her hair pulled up in braided sections with a few loose pieces framing her face, along with a berry lip and a subtle cat eye. The look was styled by Wayman + Micah.

The appearance extended what has quickly become a defined Louis Vuitton red carpet run for the actress. Louis Vuitton named Infiniti a house ambassador in December after dressing her for a series of appearances tied to “One Battle After Another,” with Nicolas Ghesquière praising both her talent and what he called her “authenticity.” Since then, she has worn a string of custom looks from the house, including a lilac ruffled gown for her Oscars red carpet debut last week.

Friday’s look also showed how much range that partnership already has. Her Oscars dress leaned lighter and more delicate, while the Series Mania gown arrived with more weight, more volume and a much stronger color statement. Both, though, kept the emphasis on custom construction and high-impact eveningwear.

Infiniti attended the Lille festival for the world premiere of “The Testaments,” Hulu’s sequel to ‘The Handmaid’s Tale,” which opened this year’s edition of Series Mania. She stars as Agnes in the MGM Television production, one of her next major projects as her breakout year continues to accelerate.
