Still trying to figure out what to dress up as this Halloween weekend? If inspiration has not yet hit,, we suggest turning to Google: according to the search giant, the most popular costume option this year is Rumi, a character from the Netflix super-hit K-Pop Demon Hunters.
Google search data reveals that Rumi is, indeed, the most trending costume idea in 2025, so we expect throngs of revelers dressed as the leader of the fictional K-pop girl band turned demon-slaying squad to be out on the town this Halloween.
Needless to say, we are not surprised: the film is uber popular and Rumi embodies a mash-up of girl-group glamour, supernatural menace and chaotic identity crisis that feels distinctly like our time. Fans love her glitter, combat boots, neon purple hair and glowing sword. Who wouldn't want to be a teen idol by day and a warrior hunting shapeshifting monsters at night?
Want to steer clear of the trendiest costumes? Stick with the standard ghouls and goblins, transform into your very own Labubu or grab your partner and recreate the Coldplay kiss-cam fiasco in your own special way. Astronaut Katy Perry is a surefire hit, Da Pope will get you plenty of shoutouts and as Victoria Ratliff you can shout "Piper, no!" all night while flitting around in a colorful caftan.
Or you might also want to go old-school, in which case you'll want to look through the most popular Halloween costumes of years past, according to Google. Here is that list:
