Look Back at Heidi Klum's Outrageous Halloween Costume Tradition

Halloween just wouldn't be the same without Heidi Klum's over-the-top annual bash, which she's hosted in both New York and Los Angeles. The location and the date (in 2012, she rescheduled due to Hurricane Sandy) may have changed over the years, but one thing we can always count on is Heidi showing up in an extravagant costume. 2014 was no different as she celebrated at Tao in NYC, wearing an elaborate butterfly ensemble and this year she's already shared a sneak peek at her voluptuous look. In years past, she's made appearances as a mouse, a gorilla, and a seriously convincing old lady, and she's gotten decked out in outrageous getups that can't really be explained.
