Madewell’s store in Brooklyn seems like any other, with tidy racks of jeans and folded sweaters artfully laid out. But here, every product has already been worn. Today, Madewell joins forces with ThredUp, the largest online consignment and thrift store, to debut a new retail concept called a “Circular Store” on the second floor of the brand’s existing Williamsburg location. Customers will be able to shop an assortment of pre-owned Madewell products, repair and tailor garments, and drop off old clothes. While the store is temporary, the two companies say it’s meant to help them explore how fashion brands can start selling secondhand products in-house, including in their brick-and-mortar locations.
