Emily Blunt Wore the Dreamiest Princess Gown to the Mary Poppins Premiere

We're still patiently waiting for Mary Poppins Returns to arrive in theaters—that will come on December 19—but the cast just gave us a stellar fashion moment to help tide us over. The movie's stars all attended the Los Angeles premiere red carpet this week, and the outfits were nothing short of amazing.

Poppins herself, Emily Blunt, stole the show at the premiere in the dreamiest princess-worthy dress we've seen in a while. Her Yanina Couture creation featured beautiful statement sleeves that took the frothy dress to the next level. Is anyone else getting bridal vibes from the stunning white dress? Another one of the film's stars, Emily Mortimer, also went for a wedding-worthy look, in an embellished white gown, while Bellamy Young opted for a sharp pantsuit of the same hue.
