Great overall shape for age, see photos. Does have some discoloration/spots and a more prominent stain on bottom. Has at least one very small seam opening on side, I don’t believe there is more than one.

I am guessing this is close to a size 6 with a small waist, check measurements

Measurements are; waist is 30 inches, arm pit for arm pit is 15 3/4 inches(31 1/2 overall rough approximate), length is 47 inches, all measurements are approximate
