Patterns From The Past: McCall's 8497 Dress Up In This Shift And Overslip

Back in 1966, you could be "Sew in with the crowd", if you made one of these dresses for yourself!
A "see-through chiffon overslip" with a slip dress underneath.
Or wear the slip dress alone for "another swinging outfit".

The back of the pattern:

Dress to impress at your next cocktail party, gala event, night at the theater, perhaps?
Or whatever type of parties people are having nowadays.
