‘Percy Jackson’ Star Dafne Keen’s Halloween Look Is a Polka-Dot Nod to ‘Coraline’ That Fits Her Horror Era

Halloween has a way of revealing what a celebrity is into, and this year’s costume parade has produced a few that feel perfectly tailored to the person wearing them. Few outfits on the internet this week have hit that mark quite like Dafne Keen’s Halloween costume, a moody, button-eyed look that has fans connecting the dots to one of animation’s creepiest classics. For an actress who has spent the past year in horror, it feels like a natural fit.

The ‘Logan’ breakout, who was born in Madrid in 2005 to actor parents Will Keen and María Fernández Ache, has built a career on playing intense, guarded characters. Fans know her as X-23 in ‘Logan,’ as Lyra Belacqua in ‘His Dark Materials’ and as Jecki Lon in ‘The Acolyte.’ More recently, she added a horror lead to that list.

Photos posted around Halloween show Keen in a black polka-dot dress with a corset-style waist and a ruffled hem, paired with polka-dot tights. She completes the look with a bright red choker, deep red lipstick, a dark sleek hairstyle and round black glasses styled like buttons. A few paper bats stuck to the wall behind her add a playful haunted-house touch.

The details appear to point to the Other Mother from ‘Coraline.’ Costume guides describe that look as a structured polka-dot dress, a dark bob, red lipstick and button-style eyes, often worn as glasses or on a headband. Keen’s styling hits nearly every one of those notes, though she has not been widely reported as naming the character herself.

The choice also taps into a very popular trend. Costume retailers have called ‘Coraline’ one of the most requested Halloween costumes in recent years, with the Other Mother’s button-eyed variant especially popular for horror-leaning parties. Even university style roundups this season recommended the film for its dark, whimsical feel and its button-eyed villains.

It’s easy to see why. The look is graphic and recognizable, it works as a solo outfit or in a group, and it leans on a few simple accessories. Button-eye glasses have become a shortcut for the whole aesthetic, and Keen’s version uses them as a stylish finishing touch rather than a full prosthetic transformation.

Keen’s costume lands during a busy stretch for her in the genre. This year she led the supernatural horror film ‘Whistle,’ directed by Corin Hardy of ‘The Nun,’ which follows high schoolers who discover a cursed Aztec death whistle that summons their future deaths. The film premiered at Fantastic Fest in 2025 and arrived in North American theaters on February 6, 2026, before streaming on March 3.

Reviews were mixed. Several critics called the story familiar, comparing it to other cursed-object and teen-slasher movies, while others praised the gory set pieces. Some singled out Keen and co-star Sophie Nélisse’s romance as a fresh element, and one viewer review even praised her “full goth mode,” which makes the Halloween photos feel like a continuation of the character.

Keen’s path from ‘Logan’ to horror is a notable shift. She was 12 when she played the feral, claw-wielding Laura in ‘Logan,’ and she carried a fantasy epic on television as Lyra before moving into Star Wars. ‘Whistle’ gave her a darker, more grounded type of role, and her Halloween look suggests she’s comfortable leaning into that image.

For fans, that makes the costume more than a simple holiday post. It’s a small, stylish reminder that she is at ease with spooky material, and it keeps her in the conversation as horror continues to attract young stars.

The images have been widely shared, with admirers praising the retro silhouette and the clever use of the button glasses. Some viewers have joked that she looks like she stepped straight out of the Other World, which is exactly what the costume appears to be aiming for.

As for what’s next, the sourcing on her upcoming projects is thin, and nothing specific has been confirmed in the reporting reviewed here. For now, the costume stands as a fun peek at her personality. Whatever she does next, it’s clear that horror suits her.
