Heidi Klum nailed her bloodcurdling look.

In fact, at her annual star-studded party held in NYC Oct. 31, the model sent shivers through the crowd when she arrived wearing an enormous—and—severed re-creation of her own left hand, complete with her wedding ring.

“I mean literally, my left hand inspired me,” Heidi exclusively told E! News on the event’s red carpet. “I looked at my hand and I was thinking, ‘How can I fit my body into this hand? There must be a way,’ and we found a way to put my body into a hand.”

As for how long the process took? Hands down, quite a while.

“Today it was about six hours to get ready,” she explained, “but obviously my team—they spent months doing this. Many people, many hands doing this hand.”

Just a month before debuting her spine-chilling costume, the Project Runway alum teased her attire, noting it would be “very, very bloody.”

But Heidi’s latest ensemble should be no surprise since the Queen of Halloween has been pulling off extravagant looks for years. As for her petrifying ensemble last October, she sported a head to tail Medusa costume, complete with an epic tail and rattlesnakes on her head.
