Nasty Gal has wrongly taken the credit for the white jumpsuit Taylor Swift wore for the Billboard Music Awards on Sunday – and it’s got everyone talking.

The fast-fashion retailer posted on its social media accounts a photo of the popstar on the red carpet, claiming that she was wearing its own “Disco Inferno” jumpsuit – except she wasn’t. Instead, she was wearing an almost-identical piece from Balmain’s spring/summer 2015 collection.

Swift, who took home eight awards on the night, was part of Olivier Rousteing’s “Balmain Army”, alongside Kendall and Kylie Jenner, Lily Aldridge and Jourdan Dunn, all who helped the designer announce his upcoming collaboration with H&M at the event decked out in the label.
