So what do we actually know about Heidi Klum's costume this year?

Mimi

Very little, and she's chosen it that way. She posted a close-up of what appears to be prosthetic organs and said the look will be "very, very bloody."

Luke

Worth noting the word "appears." The article describes the photo that way, so even the organs are an interpretation. We don't know what character this is.

Mark

When do we find out?

Mimi

Saturday, Oct. 31, at her annual Heidiween party in New York. That's Halloween itself.

Mark

Why does a costume get this much attention?

Mimi

Because she's built a record. Medusa last year, E.T. in 2024, a peacock, a giant worm, Jessica Rabbit, an elderly woman. Each one became a talking point.

Luke

Though the article is mostly a shopping guide. The "most iconic" ranking is the publication's own framing, and the viral claim about the peacock look isn't backed by any numbers.

Mark

So the retail links are the real point?

Mimi

They're the format. Each past costume gets a store-bought version, from Shrek and Fiona to a werewolf.

Luke

Right, and none of those are her actual costumes, which were far more elaborate. They're inspired-by options.

Mark

Anything about what's trending beyond Klum?

Mimi

"KPop Demon Hunters" leads, with Rumi, Mira, Zoey and Derpy Tiger, plus "Toy Story 5," "Spider-Man" and "The Odyssey."

Luke

Again, that's the article's assertion, without sales data or a source cited.

  • A close-up of apparent prosthetic organs has stirred anticipation, with Klum promising her 2026 look will be "very, very bloody."
  • The costume reveal is set for her annual Heidiween party in New York on Saturday, October 31, leaving fans waiting for the full transformation.
  • Readers are scrambling to recreate past Klum looks, from Medusa to a giant worm, using off-the-shelf pieces rather than Hollywood budgets.
  • The season is tilting toward pop culture, with KPop Demon Hunters leading the trends, and the Heidiween unveiling will land as the crowning moment.

Every autumn, a supermodel's Halloween reveal becomes a small public ritual, and this year the ritual begins with a photograph of prosthetic organs and a promise of gore. Heidi Klum, now 53, has spent over a decade turning costume-making into a kind of annual performance, and the Gainesville Sun's guide reads that tradition as a way for ordinary people to borrow a little theatrical magic. The mystery itself is simple: what will emerge at her New York party on Halloween night, and what it says about our appetite for spectacle and transformation.

A close-up photograph of what appears to be a set of prosthetic organs is the first public clue to Heidi Klum's 2026 Halloween costume. She posted it to Instagram with a warning: this year's look will be "very, very bloody."

The full reveal waits until her annual "Heidiween" party in New York on Saturday, October 31. Until then, nothing more is known about the costume.

Klum's Halloween looks have become an event in themselves, known for heavy prosthetics and transformations. The list stretches back more than a decade, from Jessica Rabbit and an elderly woman in 2013 to Medusa in 2025, with a peacock, E.T., and a giant worm in between.

The Gainesville Sun's guide suggests readers can channel those looks without a studio budget, pointing to affordable pieces for each costume. The wider season, it notes, leans toward pop culture, with KPop Demon Hunters as the biggest trend. The organs' character remains a secret until Halloween night.

A close-up photograph of what appears to be a set of prosthetic organs is the first public clue to Heidi Klum's 2026 Halloween costume. She posted it to Instagram, and she added a warning of sorts: this year's look, she said, will be "very, very bloody."

Klum, who is 53, plans to reveal the full transformation at her annual "Heidiween" party in New York on Saturday, Oct. 31, which is also Halloween itself. Beyond the organs photo and the promise of gore, nothing more about the costume has been disclosed.

The teaser lands in a season where Klum's costume has become an event of its own. The supermodel has built a reputation for elaborate, over-the-top outfits, often involving heavy prosthetics and full creature transformations, as well as instantly recognizable pop culture figures. The Gainesville Sun's roundup treats her as the reigning figure of the holiday, and pairs that with shopping links for readers who want to borrow from her past looks.

The list runs back more than a decade. In 2025 she appeared as Medusa, a look the article associates with a dramatic gown and a snake-covered headpiece. In 2024 she became E.T. In 2023 she was a peacock, a look the article says went viral, and in 2022 she showed up as a giant worm. In 2018 she and a partner dressed as Princess Fiona and Shrek. In 2017 she came as a werewolf in tribute to Michael Jackson's "Thriller" video. In 2015 she was Jessica Rabbit, in a red dress and statement gloves, and in 2013 she transformed into an elderly woman, which the piece calls one of her more surprising turns.

The article's pitch is that readers do not need a Hollywood budget or a team of special effects artists to channel those looks. For each costume it points to an off-the-shelf version, from a green-detailed Shrek and Fiona pairing to an earthworm outfit to a faux-fur werewolf. It is explicitly a shopping guide, aimed at both people planning something elaborate and those putting together a last-minute outfit.

The piece also sketches the wider costume landscape for 2026. It describes the season as dominated by pop culture, nostalgia and character-inspired looks. The biggest trend it names is "KPop Demon Hunters," with fans dressing as Rumi, Mira and Zoey from the group HUNTR/X, or as Derpy Tiger. Other popular ideas include characters from "Toy Story 5," "Spider-Man" and "The Odyssey."

The coverage is lifestyle and commercial in nature, and it does not say how Klum is making the organs or what character they belong to. The date to watch is Oct. 31, when the Heidiween party in New York is set to answer that.

This year's costume will be "very, very bloody."
