Leading luxury fashion brand Oscar de la Renta will officially end all fur sales following pressure from pop singer-songwriter Billie Eilish, who graced the Met Gala’s red carpet on Monday wearing a tulle ball gown from the label. 

Eilish, an animal rights activist who is vegan, posted images on Instagram of her at the high-profile annual fashion event in New York City wearing a nude tulle dress with a 15-foot train, writing in a caption, “It was an honor to wear this dress knowing that going forward oscar de la renta will be completely fur-free.” 

The 19-year-old, who served as the youngest ever co-chair of the Met Gala on Monday, said she was “beyond thrilled” that the fashion label’s creative directors 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.” 

“I’m honored to have been a catalyst and to have been heard on this matter,” she continued, urging “all designers to do the same.” 

Oscar de la Renta, which previously announced it would stop using fur on the runway, told The New York Times that it will now stop selling fur products in stores following years of pressure from animal rights groups. 

Alex Bolen, the brand’s CEO, has for years resisted the calls, telling the Times Monday that fur products made up “meaningful amount of sales and profit” for the company. 

Some of the pressure came even from his wife, Eliza Reed, a longtime executive at the brand, as well as Oscar de la Renta’s widow, Annette de la Renta, who reportedly told Bolen that using animal fur in fashion was barbaric.

Bolen revealed that he ultimately decided to think about changing course when Eilish’s team told the fashion company that the singer does not work with brands that still use fur in their products.

“I have to surround myself with people with different points of view,” he told the Times. 

The Hill has reached out to Oscar de la Renta for further comment. 

The company is just the latest among a series of luxury brands and designers to announce plans in recent years to phase out the use of fur, including Gucci, Versace and Prada. 

In June, Canada Goose, best known for its fur-trimmed coats, announced that it would be completely ending its use of fur by next year.
