After years of writing country-sounding songs, Sabrina Carpenter<\/a> finally made her Grand Ole Opry<\/a> debut. Dolly Parton<\/a>, Shania Twain, and Patsy Cline once stood where she stood, but Carpenter’s outfit for a night at the legendary Tennessee venue hailed from a disco-era designer.<\/p>\n Cowboy boots<\/a> are practically required at the Opry, for patrons and performers alike. For the venue’s centennial celebration, however, Carpenter styled a Cher-ish number, courtesy of the icon’s longtime collaborator, Bob Mackie<\/a>. “Thank you for the perfect dress,” Carpenter wrote to Mackie after her Opry debut, alongside a close-up of her on-stage set.<\/p>\n Mackie created a one-shoulder black bodysuit for Carpenter, featuring a blend of sequins and sheer panels. (Everyone say, “Thank you Jared Ellner<\/a>,” her longtime stylist, for making it happen.) Fringed tassels\u2014which cascaded beyond her ankles\u2014transformed it into a makeshift little black dress<\/a>. With each spin, they floated vertically to the stage, resulting in some fabulous mid-show photos.<\/p>\n
