Every Halloween, fans wait to discover what Heidi Klum will wear next. While most celebrities choose familiar characters or glamorous outfits, Klum takes a completely different approach. She transforms herself into extraordinary creations that often require elaborate prosthetics, special effects, custom-made costumes and hours of preparation. From becoming a giant worm to turning into Medusa, her Halloween transformations have become an annual talking point.
The Heidi Klum Halloween tradition reached another milestone on October 31, 2026, when she celebrated the 25th anniversary of her famous New York party with one of her strangest transformations yet: a giant, gruesome recreation of her own severed left hand. The unusual idea quickly attracted attention, but it also raised the familiar question: how does she manage to surprise everyone year after year?
Here is a closer look at her latest costume, the celebrities who attended her 2026 celebration, the famous worm transformation and some of the most memorable looks from her Halloween history.
Heidi Klum Halloween 2026: What Was Her Costume?
For her 2026 Halloween celebration, Heidi Klum appeared as a giant severed version of her own left hand. The costume was designed to look gruesome, with blood, dangling ligaments, visible veins, long red nails and her recognisable rings.
Her face was incorporated into the wrist area of the oversized hand, making the transformation particularly unsettling. She was accompanied by helpers wearing blood-stained hazmat suits, adding to the appearance of a horror-film scene.
The idea reportedly came to Klum the previous year. Looking at her own left hand, she wondered whether she could somehow fit her entire body inside a giant version of it. The final design included her engagement ring and wedding band, along with a tattoo of her husband Tom Kaulitz’s name on the ring finger.
According to the Associated Press, it took around five to six hours for Klum to get into the costume, although creating it took considerably longer. She also described carrying the heavy costume as one of the hardest parts of wearing it.
The transformation was especially fitting for the 25th anniversary of her annual Halloween party. Rather than choosing a familiar horror character, she turned an ordinary part of her own body into an elaborate special-effects creation.
Heidi Klum Halloween Party 2026: Date and Location
Heidi Klum hosted her 25th annual Halloween party on Saturday, October 31, 2026, in New York City. The celebration took place at Cathédrale Restaurant at the Moxy East Village.
The event was presented by Apothic and Butterfinger, with celebrities, entertainers, musicians and fashion personalities attending in carefully planned costumes.
The anniversary made this year’s celebration particularly notable. Klum has spent more than two decades building a Halloween tradition that attracts attention not only because of her own costume but also because of the creativity guests bring to the event.
One interesting detail is that her husband, Tom Kaulitz, did not attend the 2026 celebration because he was away on tour. However, Klum included a personal reference to him through the tattoo of his name on the costume’s ring finger.
Heidi Klum Halloween 2026 Guests: Who Attended?
The guest list included several well-known names from entertainment, music and social media. As expected, many attendees treated the event as an opportunity to create their own memorable Halloween transformations.
Some of the notable guests and their costumes included:
- Neil Patrick Harris and David Burtka: The couple dressed as the creepy twin girls from The Shining, complete with matching blue dresses and wigs.
- Kyle MacLachlan: He brought back Cliff Vandercave, his character from the 1994 film The Flintstones. He attended with his wife, Desiree Gruber.
- Chase Hudson: The influencer chose Patrick Bateman from American Psycho, giving the costume a distinctly dark, cinematic feel.
- James Charles: The beauty influencer transformed into Yzma from The Emperor’s New Groove. He said the preparation took around seven and a half hours.
- Taylor Momsen: The musician dressed as AC/DC guitarist Angus Young, reflecting her connection to the rock world.
- Questlove: He went with a San Francisco 49ers-inspired outfit.
- Paris Jackson: She was among the celebrity guests attending the anniversary celebration.
- Ice-T and Coco Austin: The couple also joined the Halloween festivities.
Klum’s children, including Leni, Johan and Lou Samuel, attended as well. The mix of horror characters, film references, music-inspired outfits and playful transformations made the guest costumes an important part of the evening.
Heidi Klum Halloween Costumes Over the Years
Klum’s Halloween reputation did not develop overnight. Since the early 2000s, she has experimented with unusual characters, dramatic makeup and increasingly ambitious costume designs.
Here are some of the most memorable transformations that helped establish her as one of Halloween’s most recognisable celebrity figures.
2000: Zombie Doll
One of her early Halloween looks was a zombie doll. It introduced the playful horror style that would become a familiar part of her costume choices.
2001: Lady Godiva
Klum took inspiration from the historical figure Lady Godiva. The look was very different from her later monster transformations, showing that she was already interested in costumes that went beyond standard Halloween outfits.
2002: Betty Boop
She brought the classic cartoon character Betty Boop to life with a recognisable retro-inspired look. It demonstrated her willingness to move between horror, animation and pop culture.
2008: Goddess Kali
One of her more elaborate and talked-about transformations was a multi-armed depiction of Kali, the Hindu goddess. The costume stood out for its scale and unusual design.
2011: Human Body Transformation
Klum continued experimenting with dramatic body effects, using an exaggerated anatomical transformation to create an unsettling appearance.
2015: Jessica Rabbit
She became the glamorous animated character Jessica Rabbit. The transformation involved extensive makeup and body-shaping effects, making it one of her most recognisable celebrity costume moments.
2016: Heidi Klum Lookalikes
Instead of becoming a fictional character, Klum arrived with several women dressed to resemble her. The idea played with identity and celebrity imitation, making the group appearance particularly memorable.
2017: Werewolf
Inspired by Michael Jackson’s Thriller, Klum transformed into a werewolf. The costume recreated the famous horror-inspired look associated with the music video.
2018: Fiona from Shrek
Klum and Tom Kaulitz embraced a couples theme, with Klum becoming Fiona from Shrek. The transformation required detailed prosthetics and green character makeup.
2019: Alien Experiment
In 2019, she chose a disturbing science-fiction-inspired transformation. Her appearance suggested an alien experiment gone wrong, complete with exposed-looking body details and special-effects makeup.
2020 and 2021: Halloween at Home
The traditional party was interrupted during the pandemic. Rather than holding the usual large celebration, Klum created Halloween-themed short films and family costumes at home.
These years showed that her interest in Halloween was not limited to hosting a celebrity event. She continued developing creative concepts even when the usual party format was not possible.
2022: The Famous Heidi Klum Worm Costume
The Heidi Klum Halloween worm became one of her most talked-about transformations.
For her 2022 party, she appeared as a giant earthworm, with a long, textured body that almost completely covered her. Her husband, Tom Kaulitz, dressed as a fisherman, completing the unusual couples concept.
The costume was so restrictive that Klum had to move around in a very different way from an ordinary party outfit. She even gave interviews while lying on the ground.
What made the worm particularly memorable was its simplicity as an idea. A worm is not an obvious glamorous or frightening Halloween character, yet Klum turned it into an elaborate costume that people still remember.
She also later appeared in a different outfit for part of the evening, showing that the worm transformation was not her only look that night.
2023: Giant Peacock
The following year, Klum went in a completely different direction. She became a giant peacock, using a team of Cirque du Soleil performers to help create the bird’s enormous tail and overall shape.
Instead of relying only on prosthetics, this costume involved coordinated human performers. It was effectively a moving group creation, making the entrance a performance rather than simply a celebrity wearing an outfit.
2024: E.T. with Tom Kaulitz
In 2024, Klum and Kaulitz transformed into characters inspired by E.T. from the classic film E.T. the Extra-Terrestrial.
The costumes included oversized heads and detailed prosthetics. Around 30 special-effects artists were involved in creating the transformations, which required extensive preparation.
The result was a matching couples costume that made both of them almost unrecognisable.
2025: Medusa
For her 2025 appearance, Klum chose Medusa from Greek mythology. Her transformation included a snake-covered headpiece, green details, unusual facial effects and a long forked tongue.
Kaulitz joined the theme as a warrior turned to stone. The matching concept gave the costume a clear story rather than treating the two outfits as separate ideas.
2026: Giant Severed Hand
Her 2026 costume continued the tradition of unexpected transformations. By turning her own left hand into a giant horror-inspired creation, Klum found a new way to combine personal details with elaborate special effects.
The wedding ring, palm lines and tattoo reference made it more than a generic severed-hand costume. It was a personalised design created around her own identity.
Why Was Heidi Klum’s Worm Costume So Famous?
The worm costume became a viral moment because it was so different from the glamorous outfits people might expect from a supermodel.
Instead of choosing a beautiful, fashionable or instantly recognisable character, Klum became an oversized earthworm. The costume covered almost her entire body, leaving her with limited movement and an unusual way of interacting with guests.
There were three reasons it attracted so much attention:
- An unexpected idea: A worm is not a typical celebrity Halloween choice.
- A complete transformation: The costume changed her shape and movement, not just her face or clothing.
- A matching story: Tom Kaulitz’s fisherman outfit gave the look an amusing second character.
The worm also demonstrates an important part of Klum’s approach: a costume does not need to be conventionally attractive to become memorable. Sometimes the strangest idea is the one people remember longest.
What Makes Heidi Klum’s Halloween Outfits Different?
The difference between an ordinary celebrity costume and a Heidi Klum Halloween costume is usually the level of transformation.
Many celebrities choose a recognisable outfit, add makeup and attend a party. Klum often begins with a much bigger concept and works backwards to figure out how to turn it into a wearable creation.
Her costumes frequently involve:
- Custom-built body structures.
- Prosthetic makeup and facial appliances.
- Special-effects artists.
- Detailed character research.
- Coordinated costumes for partners or groups.
- Long preparation and fitting sessions.
Another important detail is that she does not always prioritise comfort. A costume that changes her entire body shape can make walking, sitting and speaking difficult. The worm and giant-hand looks are good examples of how physical practicality becomes part of the challenge.
Her approach is also more like storytelling than fashion styling. The fisherman and worm, Medusa and the stone warrior, and the peacock with its performers all work because they communicate a complete idea.
How to Recreate Heidi Klum Halloween Costume Ideas
You do not need a professional effects team to take inspiration from Klum’s costumes. The trick is to focus on one recognisable idea and adapt it to your budget.
Here are a few ways to approach her most famous themes:
For the worm costume: Use a padded, curved body shape and textured fabric. Keep the design lightweight enough to move safely.
For Medusa: Create a snake-inspired headpiece, use green face details and add a simple Greek-inspired outfit.
For the peacock: Focus on a dramatic feather-inspired backpiece rather than trying to recreate the entire multi-person costume.
For E.T.: Use an oversized alien headpiece and simple clothing to suggest the character without needing full professional prosthetics.
For the 2026 hand costume: A glove-inspired design with exaggerated nails and painted veins can provide a simpler interpretation. Avoid heavy structures that restrict movement or visibility.
One useful lesson from Klum’s transformations is that a clear concept matters more than the number of accessories. Choose one central feature and make it the focus of the costume.
