This blue J Brand button-up denim shirt is made with cotton in a panelled design. It features long sleeves, flap chest pockets, topstitch detailing, a classic collar, a curved hem and buttoned cuffs. When Britney Spears had that fabulous double denim moment on the red carpet in 2001, we wished we had thought of it first. So we’re feeling lucky to have found this J Brand shirt. Now all we can say is Gimmie More.
