Chase Infiniti Wore Custom Louis Vuitton at "The Julia Set" TIFF Premiere

Chase Infiniti's breakout year keeps building momentum. The actress, who first turned heads as Willa Ferguson in Paul Thomas Anderson's "One Battle After Another," walked her first-ever film festival red carpet Friday night at the Toronto International Film Festival, premiering "The Julia Set," a coming-of-age drama from writer-director Niki Byrne in which she plays a math prodigy navigating both academic pressure and a complicated romance with her teaching assistant, played by Christopher Briney.

For the occasion, Infiniti wore a custom mini dress from Louis Vuitton, designed by creative director Nicolas Ghesquière. The piece is done in a striking chartreuse-yellow tone, covered entirely in a dense, textured fringe that gives the fabric an almost feathered, tactile quality up close. The sleeveless, boat-neck silhouette keeps the shape simple and clean, letting all the visual interest sit in the surface texture rather than the cut, while a scalloped hem finishes the look with a bit of movement. She paired the dress with sleek black ankle-strap heels and jewelry by Gabriel & Co., keeping the accessories minimal so the dress's texture stayed the focus.

She wore her natural curls pulled up into a voluminous high updo, with soft strands framing her face, and finished the glam with a smoky, defined eye and glossy lip.

Infiniti has been building a strong relationship with Louis Vuitton this year, serving as a House Ambassador for the brand and previously wearing a sculptural blush-pink LV gown at the Santa Barbara International Film Festival, plus a dramatic plum peplum gown at the BAFTAs. Speaking about attending her first-ever film festival, Infiniti said she's been trying to just take it all in, admitting it was "hard to picture" beforehand what the experience would actually feel like. Between the acclaimed reviews already coming out of "The Julia Set" and her growing fashion résumé, it's shaping up to be a big TIFF for her.
