Heidi Klum Says She'll Begin Working on Her 2023 Halloween Costume on Nov. 1: 'I Start Planning' Early

Heidi Klum is wasting no time preparing for next Halloween.

The model and businesswoman, 49, chatted with PEOPLE at her annual Halloween party in New York City on Monday evening, where she — dressed head to toe as a fishing worm — teased when she will start planning her costume for Halloween 2023.

"Tomorrow," Klum told PEOPLE exclusively, referring to Nov. 1. "When I wake up tomorrow, I start thinking of the next [costume]."

Klum, who has been known for her elaborate and over-the-top Halloween costumes over the years, detailed that this year's attire took almost 12 hours to get into. "I started at about 11:00 this morning," she explained. "So all day playing around, putting things on."

"I don't think I've ever felt as claustrophobic as I will feel that night," Klum shared at the time. "I have a thing about feeling claustrophobic."

She added, "Especially if I have too much stuck on me and can't take it off. … So I'll have to really breeze through it."

And while she said she knew the prosthetics would be a lot handle, Klum noted she was fully committed to her look — just like she is every year. "When you have it on, you can't be like, 'Oh, it's a wig and take it off,' " she told PEOPLE. "Can't take anything off. It's glued on."
