Heidi Klum Teases Bloody 2026 Halloween Costume as Fans Plan Their Own Looks

"Very, very bloody" — and only a close-up of prosthetic organs to go on
Klum's Instagram teaser for her 2026 costume reveals little ahead of the Oct. 31 Heidiween party.

So what has Heidi Klum actually told us about this year's costume?

Mimi

Very little, and she's chosen that on purpose. One Instagram close-up of what looks like prosthetic organs, and a promise that it'll be "very, very bloody."

Luke

Worth stressing the word "appears." The article says the photo appears to show prosthetic organs. That's an impression, not a confirmed detail of the costume.

Mark

And when do we find out?

Mimi

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

Why does a costume reveal get this much attention?

Mimi

Because she's made it a tradition. The guide lists looks back to 2013: an elderly woman, Jessica Rabbit, a giant worm, Medusa last year. Each one is a big swing.

Luke

Keep in mind what this article is, though. It's a shopping guide. The teaser is the hook, and the links are the point. It doesn't report on the party beyond the date.

Mark

Does it say anything about what everyone else is wearing?

Mimi

It names KPop Demon Hunters as a big trend, plus Toy Story 5, Spider-Man and The Odyssey.

Luke

Those are the article's claims about trends, with no data cited. I'd read them as a guide's impression, not a measured count.

  • A close-up of what looks like prosthetic organs has landed online, and the word "bloody" has fans bracing for something graphic.
  • The mystery is deliberately thin, with only a single photo and one comment to work from before the costume is revealed.
  • The Eugene Register-Guard is turning the buzz into a shopping guide, pointing readers toward store-bought versions of Klum's past looks.
  • The big unveiling is locked to her Heidiween party in New York on Saturday, Oct. 31, leaving only a few days of speculation.

Every autumn, the Halloween season offers a small public ritual in which a famous face slips into a disguise and invites the crowd to guess who is hiding underneath. This year the ritual has begun with a teaser: a close-up of prosthetic organs and a promise that the coming look will be "very, very bloody." The reveal waits for a party in New York on the night of Halloween itself, and in the meantime the moment becomes an occasion to remember a long line of transformations and to notice what ordinary people, in turn, choose to become.

Heidi Klum has offered the first clue to her 2026 Halloween costume, and it is a gruesome one. In an Instagram post, the 53-year-old supermodel shared a close-up of what appears to be a set of prosthetic organs and said the look will be "very, very bloody."

The full reveal arrives at her annual "Heidiween" party in New York on Saturday, Oct. 31, which is Halloween itself. Fans have only a few days to speculate before the finished transformation appears.

Klum is known for elaborate, often unrecognizable costumes, and her party is covered each year as a news event. The Register-Guard piece uses the teaser to launch a shopping guide, arguing that a showpiece or a last-minute look is possible without a Hollywood budget. Its list reaches back over a decade, from Medusa in 2025 and E.T. in 2024 to a giant worm in 2022, Shrek and Fiona in 2018, and the elderly woman she became in 2013.

The article also surveys what the wider crowd is wearing this year, with pop culture, nostalgia and characters leading the way. "KPop Demon Hunters" is the biggest trend. Still, nothing confirms what Klum's costume actually is. The organs photo and the word "bloody" are all anyone has, and the answer waits for New York.

Heidi Klum has put out the first hint of her 2026 Halloween costume, and it is not subtle. In an Instagram post, the 53-year-old supermodel shared a close-up photo of what appears to be a set of prosthetic organs. She also told fans the look will be "very, very bloody" this year.

The full reveal is set for Saturday, Oct. 31, at her annual "Heidiween" party in New York. That date is Halloween itself, so the teaser gives fans only a few days of speculation before the finished transformation appears.

Klum has built a reputation as the queen of Halloween through elaborate, often unrecognizable costumes, and her party is covered each year as a news event. The Register-Guard piece uses the teaser as a way into a shopping guide, pointing readers to store-bought versions of her best-known looks. The pitch is that no Hollywood budget or special effects team is required, whether you want a showpiece costume or something quick and last-minute.

The list runs back more than a decade. Most recent is Medusa in 2025, described as a dramatic gown with a snake-covered headpiece and bold accessories. Before that came E.T. in 2024 and a peacock in 2023, the latter noted as a viral look with colorful feathers and theatrical flair.

In 2022 she appeared as a giant worm, a full-body, exaggerated design the guide suggests will guarantee attention all night. Her 2017 Thriller werewolf paid tribute to Michael Jackson's video, and in 2018 she and a partner appeared as Princess Fiona and Shrek, a pairing the guide recommends for couples. Jessica Rabbit, from 2015, is built around a curve-hugging red dress and statement gloves. The earliest entry is 2013, when she turned into an elderly woman, which the guide calls one of her most surprising transformations.

The article also touches on what the wider crowd is wearing. Halloween 2026, it says, leans toward pop culture, nostalgia and character-inspired looks. The biggest trend named is "KPop Demon Hunters," with fans dressing as Rumi, Mira and Zoey from HUNTR/X, or as Derpy Tiger. Other popular ideas include characters from "Toy Story 5," "Spider-Man" and "The Odyssey."

What the piece does not offer is any confirmation of what Klum's costume actually is. The organs photo and the "bloody" comment are the only evidence, and the rest waits for the party in New York on Oct. 31.

The costume will be "very, very bloody" this year.
