Vintage Movie Star lingerie set NWT

Rare set of vintage lingerie with brand new tags attached! I am unsure of actual age. Tag says "Stamp of Quality Movie Star Lingerie" Store tag attached to underwear. Tag also says size Medium for both and made in USA. 100% Nylon exclusive of decoration. Faux pearl beads decorate lace. One focal point bead is centered on a iridescent clear sequin. Top is bell shaped length 24" p2p 17-18" (minimal stretch) Bottoms rise 9" hip 11" - full "comfortable" amount of stretch 20" *elastic is in fantastic shape! I've looked for comparison values. I see some Movie Star slips but no sets with underwear and not NWT.
