Here is a great McCalls coordinates pattern from 1968. It is uncut and factory folded. The envelope is in very good condition, with slight crumples at the corners.
Pattern is for a sleeveless culottes/pantdress with coordinating jacket, pants, and shorts--a whole 1960s retro outfit in one pattern! The pantdress and jacket have french darts. The pantdress has a back zipper closure.
