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.

Associate Director, Fashion News

Erin got her start as a Who What Wear intern over 13 years ago—back when the site only published a single story per day. (Who What Wear has since increased that number twentyfold.) She graduated magna cum laude from USC, which is how she ended up moving to Los Angeles from her hometown of San Diego. In college, she also interned at Refinery29, where she was promoted to editorial assistant and then assistant editor. After nearly three years at R29, she came back to WWW in 2016, where she currently holds the title of Associate Director of Fashion News (as well as the unofficial title of resident royal expert—in case you haven't noticed her numerous Meghan Markle and Kate Middleton stories). She spends her days trying to incorporate her idols, Anna Wintour and Roger Federer, into as many stories as possible. Outside of work, she loves tennis, classic rock, traveling, and smothering her dog with affection.
