Vintage 1970’s dress

Very good used condition vintage late 70’s/early 80’s dress. Dress is in excellent shape, but most of the tag is removed. What is left is Union Made in Canada. Would have had a slip, it is sheer without out. Also would have had a belt at one point as there are 2 small belt loops on the side that can be cut off. No stretch. No zips, waist is elastic and slides over the head. Fits like a XS/small. Laid flat in inches: Shoulders 14 Bust 17 Waist 13 (stretches to 15.5) Overall length 38 Sleeve 24
