1960s Herman Marcus Dallas Asian-Inspired Sheath Dress. Nubby boucle fabric, frog button closures, faux pockets on the front. Back zip, short sleeves. Unlined. There is a panel behind the button opening for modesty (visible in photo 6). In good vintage condition; the only thing I noticed was that one of the fabric loops for the hook closures at the collar is missing. The collar still closes with the remaining loop (see photos 8 & 9). I've included some photos of the nubby fabric (last 3 photos). No material or size tag, but the below approximate flat lay measurements indicate that this would best fit a Medium. Please compare them to your own to ensure proper fit:

Chest from pit to pit: 19.25"

Shoulder width: 15.5"

Waist: just under 18"

Hips: just under 19.5"

Length: 39.5"
