A new era of Billie Eilish is upon us, and along with her frosty blonde hair, the "Therefore I Am" singer is swapping out her multi-patterned wardrobe for a look that's all monochrome. Like her ensemble in the "Your Power" video, Billie's looks in her "Lost Cause" music video, which premiered on 2 June, is made up of oversized shirts and cosy loungewear in toned-back neutrals. After a closer inspection of her new style, we couldn't help but feel like Billie's outfits looked strikingly familiar. "I spy Skims," Kim Kardashian captioned a screenshot of the video on her Instagram Stories on Wednesday, and she was spot-on! Aside from a few satin looks, Billie and the dancers in the video were slumber partying it up in pieces from the Skims Cosy Collection and more. So recreating the outfits for ourselves might not be a lost cause after all (pun intended). Check out our favourite looks from Billie's new video ahead.
