Halloween season is officially here, and so is the annual ritual of checking in on Heidi Klum. Glamour has published a retrospective of her costumes, titled "25 Best Heidi Klum Halloween Costumes So Far," which covers her 2025 Medusa look and mentions a tease for what she's planning in 2026. Details on that tease are thin, so treat any prediction as fan speculation, not confirmed news.
The angle worth taking is this: Klum's costumes tell a story. Reading them in order, you can watch Halloween go from a party into a full production.
Why Klum's Halloween Is an Event
Most celebrities show up to a Halloween party in a costume. Klum's reveal has become a pop-culture event in its own right, driving costume inspiration, social chatter and celebrity Halloween coverage every year, per Glamour's framing. Glamour positions her as the reigning celebrity queen of over-the-top Halloween transformations.
That reputation is why a single teaser can set off fan theories before a single prosthetic has been applied. The anticipation is part of the product.
Phase One: The Early Years (2000 to 2007)
The list opens in 2000 with a Dominatrix look, followed by Lady Godiva (2001), Betty Boop (2002), Golden Goddess (2003), Witch (2004), Vampire (2005), The Forbidden Fruit (2006) and Cat (2007).
These are mostly recognizable archetypes: the witch, the vampire, the cat, a cartoon icon. Nothing wrong with that. It's the classic Halloween menu. But it's hard not to notice that the later costumes get much less interested in being simply recognizable and much more interested in being astonishing. That's our read, not Glamour's.
Phase Two: The Transformation Era (2009 to 2014)
After a 2008 gap in the list, the entries turn stranger and more ambitious: Crows (2009), Robot (2010), Human Body (2011), Cleopatra (2012), Old Lady (2013) and Butterfly (2014).
This is where the concept shifts. Robot and Human Body aren't characters so much as ideas, and Old Lady is a different kind of challenge entirely, since the goal is to look unlike yourself rather than glamorous. We'd argue that is the real turning point: from here, the fun is in the disappearing act, the question of whether you'd recognize her at all. The report mention of prosthetics and makeup in Glamour's framing fits that shift.
Phase Three: The Meta Peak (2015 to 2017)
The retrospective's later entries include Jessica Rabbit (2015), Heidi Klum (2016) and Michael Jackson's "Thriller" (2017).
The 2016 entry is the most fun on paper. Dressing up as Heidi Klum, as Heidi Klum, is a wink at her own status as a Halloween institution. Jessica Rabbit is a return to the cartoon-icon territory of Betty Boop, only now with more spectacle behind it. And "Thriller" is a music-video reference that fans of pop history will recognize instantly, which makes it a fitting capstone for this stretch of the list.
2025 and the 2026 Question
Glamour highlights Klum's 2025 look as Medusa, and teases speculation about what comes next. We only have the outline: there's an Instagram clue, and it's reportedly already fueling fan theories. We can't tell you what the clue says or what it points to, and we won't pretend to. If you see a confident prediction online, remember that it's a guess.
What we can say is that the pattern makes it worth watching. Klum has moved from archetypes to concepts to self-referential spectacle, and a mythological figure like Medusa suggests the ambition hasn't cooled.
How to Read the List
A note on the numbers: Glamour's headline promises 25 costumes, but the details we can confirm cover 17 of them, from 2000 through 2017, plus the 2025 Medusa mention. So consider this a guided tour of the highlights, not the complete ranking. For the full countdown, head to Glamour.
The Takeaway
The best argument for Klum's reign is the arc. She started with costumes you could buy in a bag and ended up with ones that need a team and hours in a makeup chair. Whatever she reveals this year, the real question isn't what she'll wear. It's whether we'll recognize her when she walks in.
