A frost has fallen over the Once Upon a Time set: Elsa has arrived.

Georgina Haig, who portrays the Disney icon on the hit series, has been spotted for the first time in costume on set. On Wednesday, the Australian actress was snapped face-forward in full Queen of Arendelle regalia. But how did her version of Elsa's glittery gown compare to its animated inspiration?

Leave it to Once Upon a Time's three-time Emmy-nominated costume department to put a fresh spin on the stylish look.

Georgina's ensemble mimicked many of the original dress's key features, including a wide neck with sheer sleeves, a diaphanous attached cape, lots of sparkles, and, of course, a stunning, ice blue hue. The 29-year-old thesp, who's best known for her role on Fringe also wore her hair in a sweeping side braid studded with stones in a nod to her namesake.

Still, this wasn't an exact copy. Perhaps the biggest difference lies in the fact that overall, Georgina's interpretation is somehow more princess-like and less slinky. She also completed her look with silvery ankle-strapped flats, rather than the dramatic stilettos of the animated Idina Menzel-voiced version. She's still undeniably beautiful, but she's less overtly sexy.

We're not sure whether that (rather subtle) change gives any real clues as to how the Frozen gang will fit in with the rest of the Once Upon a Time set, but we have gotten a few hints about what's coming just 'round the bend in Storybrooke.

Co-creator Adam Horowitz promised the storyline for the Frozen characters won't be a retelling of the hit movie.

"What we can say is we're very aware of what we think makes this character from Frozen so special," he revealed to E! News. "We want to honor that and make sure that what we do is in the universe that everyone fell in love with this past year."

Though his description is rather vague, a dramatic set image did post on the show's Facebook page depicting Georgina, her back to the camera, standing in a barn-like structure in the dark. Against the muted backdrop of wood walls and bales of hay, her blue cape stands out—and gives you the sense that something big is about to happen to this new addition.
