As the attempted rehabilitation of Britney Spears’ reputation goes on, the singer-tabloid star has just signed her first apparel endorsement — with Candie’s, which is sold exclusively at Kohl’s. In conjunction with her upcoming tour that kicks off today in New Orleans, Spears will be featured in a campaign that will run in print, TV, in-store at Kohl’s and online. Kohl’s and Candie’s will also be part of Spears’ promotional activities, and, in true multimedia cross-platforming, the pop star will wear Candie’s apparel, footwear and accessories in a music video off her current album, “Circus.” “There is a perfect synergy between our Candie’s girls and Britney’s fan base, and to be able to partner with her during such a monumental time in her career is very exciting for the brand,” said Dari Marder, chief marketing officer, Iconix Brand Group Inc. — without any hint of irony.
