Heidi Klum has revealed she starts plotting her next Halloween costume the morning after her annual bash ends.
Klum, 53, admitted in a Hollywood Reporter interview that November 1 marks the beginning of her creative process for the following year’s extravaganza. “I start thinking about it on Nov. 1! I usually have two or three ideas that I’m playing with and then I decide on one thing,” the mom-of-four shared.

This year’s event, held last Friday at Cathédrale Restaurant in New York City, saw the German-born model arrive dressed as her own severed left hand—a towering, blood-soaked creation that continued her tradition of increasingly elaborate transformations. Neil Patrick Harris, Paris Jackson, Kyle MacLachlan and Eric McCormack were among the celebrities who made the guest list.
But fame alone doesn’t guarantee entry to what has become one of the most exclusive Halloween celebrations in the world. Klum has enforced a strict “no costume-no entry” rule since her very first party in 2000, when she noticed attendees weren’t fully committing to the theme.
“The majority of guests were not super dressed up,” she recalled of that inaugural event. “So, after that, I implemented a ‘no costume-no entry’ rule. We quickly taught people that if you don’t come in a costume, you’re not getting in.”
The policy has produced dramatic results over two decades. “The costumes get bigger and better every year. And that’s because guests know they won’t get in unless they bring it,” Klum continued.
Her own commitment to the spectacle serves as the ultimate benchmark. “By me doing crazy, elaborate outfits as the host, my hope had always been that all my guests would follow. And it’s worked because, over the years, people have become increasingly more outrageous with their costumes,” she explained.

The 2025 gathering maintained several layers of exclusivity beyond the costume mandate. The party remained invitation-only, though one fan gained access through a charity auction where the winning bid reached $4,482. Within the venue itself, special wristbands controlled access to VIP zones. A journalist who attended the 2019 bash reported that two private areas—the back patio and the space beside the stage—were restricted to Klum’s close friends and colleagues.
Those hoping to catch the host herself faced a late night. The same reporter noted that Klum typically delays her entrance until shortly before midnight, building anticipation for her annual reveal.
Klum’s 2025 severed hand costume ranked among her most technically ambitious transformations, joining a legacy that has included prosthetic-heavy creations drawing from horror and sci-fi traditions. The preparation timeline she described—beginning November 1 and narrowing multiple concepts into one final execution—suggests the months of work required for such productions.

The Cathédrale Restaurant location in Manhattan’s East Village has hosted the party in recent years, providing the cathedral-like interior that matches the event’s dramatic atmosphere. What began as a relatively modest gathering in 2000 has evolved into a heavily produced spectacle with security protocols, tiered access and a host whose own costume increasingly competes with Hollywood special effects.
Klum’s “no costume-no entry” rule, now in its 25th year, has effectively trained an entire generation of celebrity attendees. The enforcement remains absolute: without proper attire, even A-list names face rejection at the door.
The supermodel will begin narrowing her two or three initial concepts for 2026 almost immediately, with November 1 already circled on her calendar.
