Today's pattern from the past dates back to 1970.
It's Simplicity pattern number 9112, and in the first photo, you see it worn by a model in the December edition of the Simplicity Fashion News:
The front of the pattern features another lovely model (Is it Dayle Haddon? I'm not sure... ) wearing the maxi-length version.
I am fan of this sort of old-fashioned peasant-style look from WAY back!
