Jane Justin for Don Sophisticate Vintage Dress

Approximate Measurements: Underarm to underarm: 19" Waist: 18" (flat lay) Top of shoulder seam to end of sleeve: 24" Top of shoulder seam to bottom hem: 39" Excellent used condition. Small white mark on back of garment; please see last picture. Also, please note measurements as I don't think this would be a true size 13/14 in today's measurements. This is a heavy garment. I'm guessing it's from the 1960s. Could be the 1970s.
