Bluebella Lingerie Valerian Open Bra. The Valerian open bra is inspired by the most daring lingerie desires, offering a cutting-edge hybrid of a bralette and a harness. Featuring multiple straps with braided sections and gold-tone hardware for a decadent finish, this unapologetically provocative number is certainly not for the fainthearted. Let your imagination take over, and style the Valerian bra with the matching pieces from the collection, like the harness thong or the open-back panty.
