HOLY WOW! I could not find a trace of another one of these online. However discovered some other very cool pieces by this label called Marilyn Monroe by Warners. Label reads size large although this would best fit a modern small or medium person. Blends is 84% nylon 16% spandex and 100% cotton crotch lining. It does have three snaps at the crotch. I can not believe I am selling this so get it before I change my mind!
