I could find no information about this bra on the web. Another Playtex bra with the same style number-7536- has been discontinued. The material on that one is a cotton/nylon/spandex blend jacquard while this bra has more cotton content and no nylon. The cups are seamless and unpadded. They are lined and have a hidden support sling between the layers. The straps are wide in front and adjust and stretch in back. Four back hooks.
