I am sure that there was a Vogue sewing pattern with a similar design. Here are two "copy cat" versions of that pattern from 1965-66.
McCall's 8131
circa 1965: High waisted dress w/ bateau neckline
Simplicity 6400
circa 1966: - slim dress with jewel neckline
McCall's 8154
There are dresses like that out there today - look at:
Diane von Furstenberg 'Mondrian' Shift Dress
