1930s Passementerie Light Jacket

This is such a gorgeous piece in incredible shape. No brand, size or fabric label but I am using the zipper to date it to the 1930s. One small part of the passamente ribbon detail has come up from one shoulder but a quick stitch would fix it easy peasy. Fits a small but see measurements below.

Pit to pit: 20" when zipped
Length: 18"
Arms: 24"
Shoulders: 18"
Waist: 16.5" when zipped
