Playtex 18-Hour girdles were produced in panty girdle, open bottom, long leg and all-in-one bodyshaper styles. Playtex no longer sells girdles in the United States, but a modern version of the 18-Hour line is still sold in the UK. Vintage girdles can be found from resellers.
Custom Maid's 572 and 571 long leg panty girdles provide an alternative to the Playtex 18-Hour girdle. In the UK, Playtex has replaced the 18-Hour line with its Expert in Silhouette girdles.
The Playtex 18-Hour girdle was introduced in 1967. The girdles were made from a propriety rubber blend material known as Spanette. Since the line's discontinuation, girdles are no longer made from rubber.
