Sydney Sweeney Sparks Mixed Reactions with Her Sequined Gown at the 2025 Met Gala: 'It's Not the Theme'

While the "Once Upon a Time in Hollywood" star impressed some people with her get-up for the big event, others said she missed the mark entirely.

Sydney Sweeney attended the Met Gala on May 5, 2025, in New York City and stunned in a black floor-length figure-hugging gown with a train.

The dress featured a cutout design at the chest and was bordered by a metallic ornate piece. It also had short cape-like sleeves on the shoulders. This year's theme was "Superfine: Tailoring Black Style."

This was highly emphasized by netizens, who commented on Sweeney's look for the occasion. "[sic] Dress is beautiful but not on theme," wrote one person. Another added, "The hair is the only thing closest to theme [sic]."

One asked, "Literally, why are so many people not on theme?" "Did she even try?" asked another. "Boring. Out of theme. Bye," stated one individual. Someone else remarked, "Lazy! Boring! Next."

However, some people think the 21-year-old actress looked "gorgeous." "I like [sic]," commented one fan. Another added, "She served." "Lovely dress Sydney Sweeney been killin' it [sic]" said one.

Besides her outfit making headlines, Sweeney's after–party date for the occasion also received much attention. After she walked the red carpet at the Metropolitan Museum of Art, the Washington native revealed her surprise guest: her dog Sully.

She was spotted embracing the German Shepherd pup while leaving the hotel in NY. However, it is unclear whether she attended the after-party event with the dog.
