Emma Corrin wears a goldfish dress at the premiere of My Cop.

Keeping it sweet – and a little quirky. Emma Corrin attended their last event on the red carpet in an extremely unique dress.

The Crown alum, 26, wore a JW Anderson dress designed to look like a goldfish in a plastic bag at the BFI London Film Festival premiere My police officer on Saturday, October 15. The one-shoulder dress, seemingly made of shiny, plastic fabric, was tied on one side and had a printed image of a fish swimming in water.

“WHO BELONGS TO THIS FISH? ($10 if you guess the movie),” the Golden Globe winner wrote via Instagram after the event, referencing a line from the rom-com You have mail. “Many thanks to LFF for premiering it to us My police officer here in London. I loved making this, so much heart and a good reminder of what we fought for and what we still have to fight for.”

The unusual look immediately resonated online, with Corrin’s friends and colleagues flooding her Instagram comments with praise. “You are so fit,” the singer wrote Paloma Faith. An actress Taylor Paige added: “You are unstoppable baby❤️❤️❤️❤️❤️.” Jonathan Andersonfounder and creative director of JW Anderson, left a string of red heart emoticons on the post.

The label showed a goldfish dress as part of its Spring 2023 collection, which was unveiled during London Fashion Week last month. The collection also included a dolphin print jumpsuit and dresses adorned with oversized computer keys.

Corrin, for her part, is no stranger to surrealist fashion. Earlier this year, Pennyworth alum stepped out in a Loewe dress with a balloon bodice. The UK native curates his look with the help of a stylist Harry Lambertwho also worked with Harry Styles and Josh O’Connor.

The “Watermelon Sugar” singer, 28, stars alongside Corrin My police officer, which hits theaters later this month. Based Bethan Roberts‘ novel of the same name, the film tells the story of Tom (Styles), a police officer who maintains a secret romance with Patrick (David Dawson) while he was married to teacher Marion (Corrin).

Although the film is set in the 1950s, Corrin said they liked the script because of how insightful it is about today’s struggle for LGBTQ+ rights.

“It dealt with issues that were obviously incredibly prevalent in the ’50s, with homosexuality being illegal, but I also think it speaks to a lot of issues that are still very prevalent today,” Lady Chatterley’s lover said the star Los Angeles Times in September. “I think people will go to see it thinking this is going to be something about a different time. And actually, maybe that’s what we should be talking about right now.”
