Vintage colorful short sleeve button down blouse (see measurements for sizing)

Vintage colorful short sleeve button down blouse (see measurements for sizing) Very good vintage condition. A couple of stitches have come out of collar (see photo), but can be easily repaired. Small dot on collar as well. Tag says medium, but it’s vintage so runs small. Consult measurements before purchasing. Approximate flat lay measurements: Pit to pit: 17.5” Length (center back): 21” Shoulders: 14.25”
