Husbands came and went, but Heidi Klum’s Halloween party is a pretty constant tradition for the supermodel and “Project Runway” host. The German-born beauty puts a lot of thought into her costumes, and tops herself almost every time.

“I start thinking of ideas months before Halloween, and I have an amazing team who makes the impossible possible. I don’t really have a system for picking my costume each year, they just kind of come to me. It’s definitely not a last-minute decision. It takes months of preparation,” Klum told Parade magazine.

Check out Heidi Klum’s craziest Halloween costumes in anticipation of the stunning idea she’ll probably pull out for this year’s Halloween party.
