Heidi 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 "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 ????
