This is an original, rather rare 1920s dress pattern by Butterick.
"Juniors' and Girls' Slip-Over One-Piece Side or Accordion-Plaited Dress with Straight Lower Edge."
The dress includes stylish contrasting neck and armhole bands, 2 neckline options, and a sash belt tie. The pattern includes instructions for making the "String Girdle and Flower" ornament as illustrated.
Condition: The pattern came to me crumpled into a ball and stuffed inside the envelope. At some point, it was exposed to moisture and developed some crinkling and watermarks. However, I have carefully ironed it flat and verified that the pieces are in working, tidy shape. It is now in very strong, ready-to-use condition! The instructions also have some staining from this moisture but everything is still quite legible and usable. There is no musty smell or mold present.
Complete: The instructions are missing. All pattern pieces are present.
Pattern type: un-printed tissue.
