this is a vintage bustier. It is all sequins. It has a couple areas where a sequin is missing and is slightly darkening the sequins but is otherwise completely intact and absolutely gorgeous.You will not find this kind of vintage pin-up wear very often in this great of shape. It does velcro in the back with some elastic. there is no size but I wore this when I was a 36 c. Please see measurements in photos. now that my implants are out I can no longer wear it. My loss is your gain. I'm sad to let it go. please ask questions. please see pictures
