Heidi Klum's 16th Annual Halloween Party sponsored by GSN's Hellevator And SVEDKA Vodka At LAVO New York - ArrivalsHeidi Klum always wows with her Halloween costumes, each year donning an outfit more complex and amazing than the last. But the supermodel may have officially outdone herself this year with a jaw-droppingly perfect -- and insanely sexy -- take on Jessica Rabbit.

Klum went all out in her transformation into the "Who Framed Roger Rabbit" cartoon bombshell (she's not bad -- she's just drawn that way), donning prosthetics all over her body -- from her lips and her eyelids to her hips, breasts, and derriere -- to make her look as accurate as possible. She completed the complicated transformation with a red wig, purple gloves and eyeshadow, and a stunning, slinky, cut-to-there red-beaded gown, courtesy of her former "Project Runway" protege, designer Christian Siriano.

The entire, painstaking process was documented on Klum's Instagram page, where she posted tons of photos and videos of her transformation. (Siriano also shared a few fun shots of Klum's fitting, featuring her prosthetic curves, as well as some pics of the finished product.) Check out a few below, and revel in the awesomeness. Klum may need to retire from throwing her epic Halloween bashes, because we honestly don't know how she could possibly top this awesomeness next year. But we can't wait to see her try.

#heidiHalloween Such a fun night 💋
