2000
Heidi started out in the grand tradition of A Bewigged Version Of Herself. By her own admission, she was being "Heidi, but a little bit more S&M."
2001
Her second year, she upped the ante and went as Lady Godiva, arriving on an NYPD horse to boot. But in many ways, this is still just a wig and a tight costume, and I guess the occasional mammal, but not as OTT as we're going to get.
2002
Betty Boop is fun, and the makeup is a hint at how far she's willing to go for a costume. The Internet tells me she also added bigger fake boobs.
2003
This is "Space Alien," for which she made herself entirely gold. Even, apparently, her teeth. Some designers at Victoria's Secret made this for her, which may explain why it's squeezing her boobs like a tube of toothpaste.
2004
This is "witch," but really, it's so much more. It's the version of The Wizard of Oz that exists in a Twisted Sister video.
2005
And here we have VAMPIRE. I feel like nowadays it would be a more elaborate construct, like CHER HAS TURNED BACK TIME TO THE ERA OF TRANSYLVANIAN ORGIES.
2006
This costume, which is Eve and the serpent and the fruit in the Garden of Eden, was particularly brilliant because she was right about to give birth. I love how creative this is...
2007
... which is why "cat" was rather a comedown.
2008
Here, she is the Hindu goddess Kali, an undoubtedly intricate and striking costume, but also one that made a lot of people very unhappy. I guess she was in India and her assistant was like, "Ooh, go as a scary goddess," and Heidi was like, "Neat," and that was that. I feel like... going as Eve and the snake is one thing, but being like, "Haha look at this FREAKY-ASS GODDESS" is not so culturally sensitive.
2009
Heidi had just had a baby earlier in this month. I don't know if she's a raven or a crow, but I cannot think of anything I would have wanted to squeeze into LESS after just delivering a baby.
She's with Seal here, and I truly don't know why he went with the boutonnière. His seems like it was made with leftover material and it wasn't QUITE enough.
2010
This is "robot," but I like to think of it as Elektra from Starlight Express.
2011
There seem to be two costumes from this year: She and Seal did this, which creeps me the F out...
2011
And then she went as that Body Worlds exhibit where you see skinned corpses, and honestly, it's icky but I infinitely prefer it to her gorilla nipples.
2012
This is Cleopatra. She has crystals all over her face. I do not THINK she has darkened her skin; it seems like just some gold paint around the sparkles. Also, when I zoomed in, she has a real Angry Melania vibe to her.
2013
It's Granny Klum!
2014
This is amazing, and one of my favorites. She's a butterfly, and it's BRILLIANT.
2015
Gigi nailed the Sandy from Grease hair, but damn, the makeup work on Heidi that transforms her into Jessica Rabbit is really outstanding. And eerie. I think I am seeing waxed pubis though.
2016
This is supposed to be her army of lookalikes, all of whom look slightly different, and some of whom look truly wacky.
2017
I keep thinking OH LOOK, TEEN WOLF, but then I read it was supposed to be someone from the Thriller video. Either way, I love her lack of vanity.
2018
I believe this is her current husband, helping with Shrek to her Fiona. Shrek is basically how I feel right now after lo these many months of quarantine.
2019
I think this is Zombie Alien Who Ate Astronaut Tom Kaulitz and it is CREEPY AS HELL and a pretty high note on which to end this sucker. Cross your fingers that she does it for the 'gram this year.
