Taylor Swift was renowned for her Fourth of July parties in the past, but now it's all about New Year's Eve bashes- in COSTUME no less.

The Reputation star has posted an image to Instagram featuring a slew of celebrities dressed as their childhood heroes, and it's pretty damn unreal.

The singer dressed as Ariel from The Little Mermaid, and we're sure many of her fans may just rush to get her gorgeous red hair and emerald sequin lewk…

She captioned the post:

“Mary Poppins, Audrey, Ariel, Ms. Frizzle, Cinderella, Gwen Stefani, Mr. Toad, Avril, Nancy Drew, Posh Spice, Rizzo, Frida Kahlo, Steve Irwin, Dorothy, " she wrote, alongside four star-studded images.

“This new year we decided to dress up as our childhood heroes. Sending you all love and hope going into 2019."

The party featured Blake Lively, Ryan Reynolds (being his gas self) and Gigi Hadid, among others, and our FOMO is real.

Just LOOK at how insanely good Gigi Hadid werks the Mary Poppins costume:

No fair.

Where were our invites, though? Must have been misplaced with all the Christmas post and fan mail…

This is a party we'd KILL to attend. Keep slaying, Taylor. With the Grammy's approaching, the star is sure to achieve even more fierceness in 2019.
