I was surprised to find on Google (totally by accident) that an actress Julie Newmar (born in 1933, played the original cat woman) came out with a pantyhose patent in the ’70s for shaping the behind, being ultra-sheer, and ultra-snug.
At least by what I found on Google, it looks like that patent was renewed in the year 2000. So I guess it’s still being produced.
I’d love to meet her some day! Even though she is in her 80’s now, she seems to be quite active. It’s possible, I am not joking… I recently met up in Vancouver with Kecia Nyman, a supermodel from the 60’s. We even went out for some cappuccino and cakes on Granville Island. Who’d think of that, eh?
Her First Patent:
Patent number: 3914799
Filing date: Sep 25, 1974
Issue date: 1975
Update: as it is noted below by David from United States, Julie Newmar got famous through a Broadway musical called `the silk stocking`. Here is the vintage poster picture I found from that show.
