How Billie Eilish's Met Gala Dress Is Making A Huge Change In The Fashion World

The Met Gala took place on September 13, with a theme of "In America: A Lexicon of Fashion." Actors, models, influencers, and other stars showed up to The Metropolitan Museum of Art in over-the-top and jaw-dropping ensembles. And while everyone is talking about their favorite looks of the evening, there is one, in particular, making waves due to the way it's making changes in the industry.

Billie Eilish donned a gown fit for a fairytale princess, which was created by Oscar de la Renta and inspired by a dress Marilyn Monroe wore to the Oscars in 1951 (via Vogue). 

"She had always dreamed of wearing a proper ball gown — particularly something corseted, thanks to her love of Barbies growing up — but she thought that it might be in an acid-green colorway or something along those lines. After her British Vogue cover, though, her style began to evolve," said British Vogue style director Dena Giannini, who styled Eilish for this event. "After reviewing about a million images together, she and I decided that it had to be Oscar de la Renta for the Met Gala. I called [creative directors] Laura [Kim] and Fernando [Garcia], and within 10 minutes, we'd agreed to collaborate together."

There is a twist, though: Billie Eilish, who is a vegan and an animal rights activist, said she would only wear one of Oscar de la Renta's gowns if the brand would stop selling fur clothing items (via The New York Times).

"I am beyond thrilled that @fernandogarciam1205 and @tokibunbun and the entire team heard me on this issue and have now made a change that makes an impact for the greater good, not only for animals but also for our planet and environment, too," Eilish wrote online. "I'm honored to have been a catalyst and to have been heard on this matter. I urge all designers to do the same."

The singer promotes more changes through her Instagram account, where she has encouraged her followers to go vegan, discussed the environmental benefits of this lifestyle, and shared her Taco Bell order of 20 bean burritos (via
