Meg RyanMeg Ryan attends the 2025 Oscars. Frazer Harrison/Getty Images Though Ryan looked cool and comfortable, a few simple tweaks could have improved her red velvet look.A chic updo would have complemented the elegant style of her strapless gown, and thinner shoes would have clashed less with its heavy fabric.Mikey MadisonMikey Madison attends the 2025 Oscars. Arturo Holmes/Getty Images The "Anora" star's Dior dress had a black bodice and a pink empire-waist skirt with a bow and a train.The dress was pretty, but ultimately overdone. Numerous stars have worn versions of the same look.Stronger embellishments on the bodice or a different color combination could have enhanced the ensemble.Ethan SlaterEthan Slater at the 2025 Oscars. Monica Schipper/Getty Images The "Wicked" star walked the red carpet in a black tuxedo, a white button-down, and a solid tie. He also wore shiny dress shoes.Though his outfit was classic, it was also forgettable especially compared to the standout looks worn by other members of the film's cast.Lily-Rose DeppLily-Rose Depp attends the 2025 Oscars. Savion Washington/Getty Images Depp embraced the aesthetic of "Nosferatu" in a black lace gown that was custom-made for her by Chanel.That said, the sheer ensemble seemed a bit too casual for the glamorous event. It would have been better for an Oscars after-party.Rachel ZeglerRachel Zegler attends the 2025 Oscars. Gilbert Flores/Getty Images Zegler's custom Christian Dior gown was pretty, with pearl details and gray tulle.However, its top didn't seem to fit the "Snow White" star. It also had a visible tan corset piece that could have blended better into the garment.Joe LockeJoe Locke attends the 2025 Oscars. Savion Washington/Getty Images Locke, who is in the Netflix series "Heartstopper," wore an assortment of colors and pieces that ultimately didn't work together.They included a white blouse with a matching bowtie, a long vest covered in gold sequins, gray trousers with sharp pleats, and a black suit jacket with tails.Storm ReidStorm Reid attends the 2025 Oscars. Arturo Holmes/Getty Images Reid, best known for "Euphoria," made a statement in a red Alexandre Vauthier minidress with a matching cape and gold belt.Unfortunately, it looked more like a designer Little Red Riding Hood costume than an Oscar-worthy outfit.Rachel SennottRachel Sennott attends the 2025 Oscars. Gilbert Flores/Getty Images The large, pink sequins that decorated Sennott's strapless gown dated her look. Similarly, her black, knee-length boots didn't feel cohesive with the dress.Smaller sparkles and more sophisticated accessories could have elevated the ensemble.Sennott recently appeared in "SNL," the movie about the origins of "Saturday Night Live."Elle FanningElle Fanning attends the 2025 Oscars. Monica Schipper/Getty Images Fanning, who played Bob Dylan's girlfriend Suze Rotolo in "A Complete Unknown," is a consistent style star, but her latest Oscars look was underwhelming.Givenchy custom-made her white, sleeveless gown which had a full lace skirt, a black bow belt, and a deep sweetheart neckline.Her Cartier necklace was eye-catching and glamorous, but it made a bigger statement than the rest of her ensemble.Whoopi GoldbergWhoopi Goldberg attends the 2025 Oscars. JC Olivera/Getty Images Christian Siriano designed her Cinderella-esque ballgown.While its off-the-shoulder sleeves and classic silhouette suited Goldberg, its shiny fabric distracted from the overall look.H. E. R.H.E.R. attends the 2025 Oscars. Frazer Harrison/Getty Images The musician chose a statement-making gown in an off-green shade. It was decorated with silver sequins, accessorized with a brown belt, and had a raw hem.Unfortunately, the top of the gown was too prom-like, while its bottom half looked messy and unfinished.Monica BarbaroMonica Barbaro attends the 2025 Oscars. Mike Coppola/Getty Images Barbaro, who starred in "A Complete Unknown," sported a custom gown from Christian Dior.The dress had potential, but it ultimately fell short. Its full pink skirt was wrinkled, its corseted waist sat just a touch too high, and its sparkling bralette top appeared to be ill-fitting.
