The style, which has been spotted on red carpets and streets alike, combines the beloved '90s neck accent with a plunging neckline. But just how low that does that neckline go? That's totally up to you! You can show a modest amount, like Gomez, or bare your front and back, à la Jenner.
And the best part? It's just the right amount of sexy for that New Year's Eve party coming up.
To see how celebs are rocking the choker neckline, watch Red Carpet Daily, presented by AT&T. And keep watching to see Gigi Hadid's Aspen street style and Daisy Ridley's latest (and last!) Star Wars: The Force Awakens ensemble.
