The supermodel shared a glimpse of her outfit for this year's celebration on Instagram. "
Last year Heidi dressed as Jessica Rabbit, and rocked a LOT of prosthetic's to pull it off.
What's cooler than a freaking huge butterfly?!
A really old lady, that's what's cooler! Heidi slayed with this grandma vibe.
This was potentially one of the most OTT looks Heidi ever rocked, and it was phenomenal! Bow down to Cleopatra y'all!
This bloody amazing look wowed fans.
Robo-Klum was a major hit... and freakishly tall!
This vampire-burlesque mix was scarily odd, but we loved it all the same!
Don't know what the hell she was, but it doesn't mean we didn't love it. This golden masterpiece was absolutely jaw-dropping.
This has to be one of Heidi's crowning achievements, she looks EXACTLY like the famous Miss Betty Boop.
