Designers, stylists, and models play dress-up all year long. So if anyone knows how to do it up for a costume party, it's this set. As our treat to you, here's a look at how the world's most fashion-forward folks dressed for Halloween this year.
1. Cindy Crawford
2. Marc Jacobs
Marc Jacobs was hardly recognizable as a female bodybuilder he named "Stacie." But, like Marc, Stacie has good taste: she had her nails done by fashion's favorite nail artist, Jin Soon Choi. And, the legendary Pat McGrath helped her out with makeup.
3. Christian Siriano
The Project Runway alum did a couple's costume with his new husband—and the duo did not skimp on pattern. "We are your midnight hallucination," Christian captioned a pic. Well, that beats your average cat or witch.
4. Martha Hunt
Victoria's Secret Angel Martha Hunt channeled Michelle Pfeiffer's sexy Scarface character, Elvira Hancock. She even called in help from a pro stylist, Lindsay Kate Grosswendt.
5. Delilah Belle
Lisa Rinna's model daughter made a perfectly provocative devil. "Didn't even have to dress up for Halloween," she cheekily captioned a snap.
6. Rachel Zoe
The stylist and fashion designer dressed as Edie Sedgwick; her husband Rodger Berman completed the theme with an Andy Warhol getup.
The duo's sons, Sky and Kaius, made perfectly convincing (and adorable) "batboys."
7. Brad Goreski
Rachel's former protégé Brad Goreski topped his Lady Gaga costume with the singer's new signature accessory: a baby-pink, wide-brim hat. Riffing off Lady G's new album Joanne, the stylist named his look "JoManne."
8. Taylor Hill
She may be an Angel IRL, but Taylor Hill certainly didn't dress like one for this weekend's spooky parties. We're especially freaked out by those bloody horns.
9. Alessandra Ambrosio
Alessandra smoldered as a sparkly Jessica Rabbit.
She sealed the look with a glittering, ruby-red kiss.
10. Lily Aldridge
As Holly Golightly, Lily Aldridge did justice to a classic costume. She even toted along a coffee cup and breakfast in a bag, making the look extra authentic to the Breakfast at Tiffany's film. Anyone else have a powerful urge to hear Moon River?
