1955: Guys and Dolls

The movie opens with LARRI THOMAS & BETH CARTER as "Goldwyn Girls"

When they can't get the attention of the boys in skirts, they switch to tight pants...

That do the trick quite nicely...

The Warner Twins (Sandra & Sonia)...

Sandra went on to become a provocative album cover model for Martin Denny records in the late 50s...

And even wound up singing on one of her own...
