August may traditionally be one of Hollywood’s quieter months, but the 2026 film calendar has delivered plenty of red-carpet fashion worth watching. From maternity dressing that breaks the rules to archival glamour, sculptural couture and deliberately undone New York style, celebrities have embraced a surprisingly diverse fashion vocabulary while promoting their latest films.
Here are 10 of the strongest celebrity movie-premiere and promotional looks of August 2026:

Anne Hathaway – Custom Atelier Prabal Gurung
Anne Hathaway turned the Los Angeles premiere of “The End of Oak Street” into a lesson in modern maternity dressing. On August 9, the actress stepped onto the carpet in a custom Atelier Prabal Gurung look consisting of a dramatic cropped halter top with a cascading train, paired unexpectedly with low-rise jeans and Aquazzura pumps. Rather than concealing her pregnancy, Hathaway made her baby bump the focal point of the look. The juxtaposition of couture-inspired drama and relaxed denim gave the ensemble a youthful, fashion-forward attitude—and proved that maternity dressing does not have to mean sacrificing personal style.

Sadie Sink – Vintage Alexander McQueen
Sadie Sink continued her extraordinary 2026 fashion run at Disney’s D23 Entertainment Showcase in Anaheim, where she celebrated her casting as Jean Grey in the upcoming “X-Men” film. The actress wore an archival Alexander McQueen gown from the designer’s spring 2003/”Deliverance” collection. The gauzy, ethereal construction and delicate detailing created an almost otherworldly effect, while Sink’s signature red hair added an arresting contrast. Styled by Molly Dickson, the vintage look felt both historically significant and remarkably contemporary. Although technically a Disney promotional event rather than a traditional movie premiere, it was unquestionably one of August’s most memorable film-related fashion moments.

Demi Lovato – Vintage Dolce & Gabbana
Demi Lovato brought nostalgia and sensual glamour to the “Camp Rock 3” premiere in Los Angeles on August 10. The singer and actress chose a vintage Dolce & Gabbana dress from the 1990s, featuring a bronze satin finish, fitted midi silhouette, halter neckline and lace-up bodice. Matching pointed-toe pumps completed the look, while her deep side part added another touch of throwback glamour. The styling was especially appropriate for the occasion: almost two decades after the original “Camp Rock” films, Lovato returned to the franchise looking like a grown-up version of the Disney star audiences remember.

Charlize Theron – Custom Celine
Charlize Theron closed out “The Odyssey” promotional tour in spectacular fashion at the film’s Seoul premiere on August 4. The actress wore a custom Celine black satin gown with a high neckline, sculptural midriff cutout and dramatically elongated panels flowing from the shoulders. The streamlined column silhouette gave the dress a futuristic quality, while Celine lace-up shoes and sleek sunglasses added an unexpectedly modern edge. A dramatic Dior diamond ear cuff provided the finishing touch, turning an otherwise minimalist look into a statement of sophisticated glamour.

Monica Bellucci – Custom Fendi
Monica Bellucci reminded everyone why she remains one of cinema’s most enduring style icons at the Locarno Film Festival, where she promoted “Ketticè” in August. For the film’s premiere, Bellucci wore a custom Fendi off-the-shoulder black lace gown designed by Maria Grazia Chiuri. The floor-length silhouette embraced the actress’s signature Italian glamour without feeling dated. Black lace has long been part of Bellucci’s fashion vocabulary, but here it felt less like repetition and more like refinement. With its elegant neckline and figure-skimming construction, the gown allowed the actress’s presence to remain the center of attention.

Ella Rubin – Louis Vuitton
Ella Rubin made an impressive designer debut at the New York premiere of “Sterling Point,” a promotional carpet for the Prime Video project on August 3. The young actress wore a minimalist white Louis Vuitton jersey halter neck dress. The simplicity of the silhouette allowed the tailoring and clean lines to speak for themselves, while the stark white palette gave Rubin a fresh, modern red-carpet presence. Rubin is quickly emerging as one of the younger stars to watch on the fashion circuit, and this understated Louis Vuitton moment demonstrated that she makes minimalism feel just as impactful as a heavily embellished gown.

Geena Davis – Vibrant Orange
Geena Davis brought a welcome dose of color to the Los Angeles premiere of “The Wrong Girls” on August 5. The veteran actress chose a vibrant orange minidress that immediately stood out against the traditional sea of black, white, and metallic red-carpet dressing. She paired the playful look with an especially memorable novelty accessory: a fish-shaped handbag. At 70, Davis demonstrated that red-carpet glamour does not have an expiration date. The bright color and whimsical accessory gave the ensemble a sense of fun that was perfectly suited to the film’s irreverent spirit.

Kristen Stewart – Leather and Sneakers
Kristen Stewart took a very different approach to film-promotion dressing while making the rounds for “The Wrong Girls” in New York City. Rather than embracing conventional premiere glamour, Stewart leaned into the rebellious aesthetic that has become synonymous with her personal style. One of her standout August appearances featured a sleek black leather dress styled with sporty Adidas footwear, creating a deliberate clash between polished luxury and downtown nonchalance. Her promotional wardrobe has continued to embrace that tension between masculine and feminine, polished, and undone. It is precisely what makes Stewart such an interesting fashion presence: she rarely looks as though she is dressing simply to satisfy the expectations of a red carpet.

Leslie Mann – Magda Butrym
Leslie Mann offered one of August’s prettiest transitional looks while promoting “Spa Weekend” in New York City. The actress wore a white lace midi dress by Magda Butrym, combining a Victorian-inspired romanticism with a contemporary silhouette. Red accessories, including pointed shoes and a coordinated lipstick, gave the otherwise delicate white look a sharper, more fashion-conscious finish. The result was an ideal late-summer outfit: feminine and light enough for August, but sophisticated enough to hint at the beginning of fall dressing.

Olivia Wilde – Alberta Ferretti and Fendi
Olivia Wilde brought a cooler, more directional sensibility to the Locarno Film Festival while promoting “The Invite.” For the film’s photocall, Wilde wore an Alberta Ferretti Resort 2027 black leather-and-lace strapless peplum top with straight-leg denim. The combination balanced sensuality with relaxed festival dressing, allowing the actress to look polished without appearing overly formal. The look was a reminder that some of the best film-festival fashion happens away from the main evening gown carpet. Wilde’s mix of leather, lace and denim felt contemporary, confident and unmistakably summer 2026.
