Billie Eilish wore Oscar de la Renta at the Met Gala under one condition: They stop using fur

Billie Eilish stunned in a peach gown with a long train that cascaded down the steps of the Met Gala on Monday night – and her Marilyn-Monroe inspired look came with some conditions for designer Oscar de la Renta. The fashion house is going completely fur free, per Eilish's request.

"It was an honor to wear this dress knowing that going forward Oscar de la Renta will be completely fur-free!!!!" Eilish, who co-chaired the gala, wrote on Instagram, sharing shots of the stunning dress at the fashion gala.  The 19-year-old said she is beyond thrilled that creative directors Fernando J. Garcia and Laura Kim, as well as the whole Oscar de la Renta, team heard her 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."
