The 2025 Transformation: Medusa, The Terrifying Mythological Creature
For her highly anticipated 2025 "Heidiween" party, Heidi Klum once again proved her commitment to the macabre by transforming into the fearsome mythological figure, Medusa.
Klum had teased the costume would be "very ugly," and she certainly delivered a terrifying, monstrous look.
The final Medusa costume featured an elaborate, scaly green and gold bodysuit that covered her from head to toe.
The most striking elements were the prosthetics, which gave her a reptilian face, and the intricate headpiece featuring a terrifying nest of snakes in place of her hair.
Adding to the horror, the costume included a rattlesnake tail, completing her metamorphosis into the creature whose gaze could turn men to stone.
Her husband, Tom Kaulitz, often joins her in a complementary costume, but for this year, all eyes were on Klum’s terrifying solo transformation, which debuted at her annual New York City bash on Friday, October 31st.
The Anatomy of Transformation: Three Recent Iconic Costumes and Their Creation
Klum's costumes are not merely outfits; they are feats of engineering, makeup artistry, and prosthetic design, often taking months of collaboration with specialized teams. This dedication to detail is what gives her "Heidiween" its topical authority and cultural relevance.
1. 2024: E.T. Phone Home! (The Year-Long Project)
In 2024, Klum and her husband Tom Kaulitz debuted a heartwarming yet complex duo costume as E.T. and an alien handler.
The construction of the E.T. costume was a year-long process involving a team of 30 artists.
The process began with digital scans of both Klum and Kaulitz’s bodies and faces, a modern technique used to ensure the perfect fit and realistic, lifelike alien texture.
The final E.T. look was a massive, realistic costume that perfectly captured the beloved alien, proving that her costumes can be sweet as well as scary.
2. 2023: Giant Peacock (The Cirque du Soleil Collaboration)
The 2023 costume saw Klum transform into a spectacular, vibrant Giant Peacock, a look that required an immense wingspan and a massive team effort.
This elaborate costume was a collaboration with the world-renowned performance group, Cirque du Soleil, showcasing the level of professional artistry involved in her looks.
The costume featured a massive, intricate tail of feathers that required a huge team to maneuver and support, turning her into a living, breathing spectacle on the red carpet.
3. 2022: The Infamous Worm (The Four-Month Construction)
Perhaps her most shocking and memorable costume in recent history was the Giant Worm in 2022.
This look was a masterclass in commitment, as it rendered her almost immobile, forcing her to wriggle along the ground and be helped up by her husband, who was dressed as a fisherman with a hook in his eye.
The prosthetic worm costume took four months to construct and then an additional 10+ hours on the day of the party for the application process.
Klum spent nine hours in the makeup chair for the hand-painted details alone, a process she documented extensively on social media, giving fans a rare glimpse into the sheer labor involved in her legendary transformations.
The Lore of Heidiween: A History of Dedication and Shock Value
Heidi Klum's annual Halloween party, or "Heidiween," began in 2000 as an experiment after she noticed a lack of genuinely "cool" Halloween parties in the celebrity circuit.
Her dedication to the holiday is so intense that she has missed the party only a few times, notably in 2009 due to pregnancy and in 2020/2021 due to the global pandemic.
The party has grown from a small gathering to a lavish, celebrity-filled event, often held at iconic New York City venues like the nightclub Marquee, attracting around 500 guests.
The costumes are the star of the show, with Klum consistently delivering looks that push the boundaries of special effects and body modification.
Other Notable Transformations: Topical Authority Entities
- 2018: Princess Fiona (Shrek): A massive, green-skinned ogre prosthetic, complete with husband Tom Kaulitz as Shrek.

Heidi Klum’s commitment to her Halloween persona is unparalleled in the celebrity world. Every year, she doesn't just put on a costume; she undergoes a complete, often uncomfortable, and always spectacular metamorphosis.
Her latest Medusa costume in 2025 continues a two-decade-long tradition of spectacle, reinforcing her legacy as the ultimate Halloween Queen and an artist of the impossible. The anticipation for what she will reveal next year is already building, a testament to her enduring topical authority in the world of costume and celebrity culture.
