K-pop Halloween Costume Ideas 2025

Spooky season is here! Whether you’re heading to a party, a K-Pop club, or just want to dress up spookily, we’ve got plenty of spooky outfit ideas for you to choose from, inspired by idols, music videos, and stage performances.

ATEEZ “Wonderland” ghouls

If you’re a makeup buff, ATEEZ’s 2019 M Countdown stage might be an interesting choice for you. The boys showed off a variety of looks inspired by everything from clowns to DC’s The Enchantress. They even showed off a Halloween version of their ‘Wonderland’ military outfits, complete with white gloves and full clown makeup.

Seulgi in “Feel My Rhythm”

If you’re in love with Seulgi’s glamorous look, be sure to stock your wardrobe with some bold pieces like a black long-sleeved turtleneck and high-waisted shorts. Shiny black knee-high boots or stilettos will complete the look with a striking fashion statement. Finish the look off with chains, a crown, and a faux fur scarf if you have one! You’re sure to turn heads in this Kpop Halloween costume!

BTS Halloween Costume Ideas

BTS donned costumes for the music video for their B-side track “Dope,” a song that encourages everyone to never give up and pursue their dreams. They took on the roles of various professionals, including doctors, police officers, and race car drivers. Playing someone different from yourself is always good, and Halloween is the perfect excuse to do just that.

Red Velvet Halloween Costume Ideas

Red Velvet always manages to excite us, and we never know what we’re going to get, but it’s nothing short of brilliant. Sure, they have a bright and colorful side, but at least half of their concepts have a dark and gritty tone to them. They even have their own Halloween-themed music video for “Really Bad Boy,” which takes inspiration from The Shining, complete with spooky themes and decorations, and of course, a big bad wolf.

We also have the song “Psycho” which perfectly captures the gothic and witchy spirit, both in the lyrics and in the video. We understand the depiction of a young girl with mental issues, always plotting and scheming in her flawless black and white outfits, and one of the simplest yet most terrifying styles of this concept is a white evening gown paired with black lipstick, the perfect combination for Halloween.

K-pop is full of costumes and glitz, perfect for the spooky season. No matter how you choose to celebrate Halloween, we hope you have a spooky time!
