What do French shoe label Repetto and Earnest Cut & Sew have in common besides being cult favorites of fashion insiders? Well, come September 1, the two are joining retail forces with a 90-day pop-up store within the denim brand’s Meatpacking District lifestyle and concept shop. The collaboration marks the first-ever retail initiative in the U.S. for Repetto, a dance apparel company that has come a long way since Rose Repetto designed her first ballet slipper in 1947. Since then, the simple slipper has gone from stage to street with the help of some of its most famous fans, like Brigitte Bardot. The temporary store will feature an extensive selection of shoes, boasting over 70 styles in 350 different finishes. In addition to the classics, Earnest Sewn president and designer Scott Morrison has created a one-of-kind Repetto Zizi “jazz” model that will be exclusive to the store. A number of celebrity supporters are also on board to add their names and signatures to a limited number of one-off artist-signed Repettos. And as if that’s not enough hullabaloo, as part of Earnest Sewn’s upcoming eco line Greencaste, two exclusive styles of the Zizi and the BB will be cast in organic canvas. Earnest Sewn will christen the collaboration with a party during Fashion Week, but as with all things pop-up, come December 1, both the installation, and likely the shoes, will be gone.
