This is a classic  maxi dress from mid-60's/70's. It was made by J-S-E Inc California a nd the tag says size 14 (see measurements in details, though, because sizing today is different than the 70's. It is a poly/cotton blend with a full rayon lining.   Button flosure in front. No major stains or blemishes I could find.  It is a Vintage item, so there is wear and it is not to be expected to be in "new" condition.  It is a lovely piece of the past.

Chest - 38-40"
Shoulder to shoulder across back: 16.5"
Waist: 29-32" (there is elastic in front, so it isn't super fitted.
