Button up crochet embroidery top button sleeves

Alfred Dunner Labeled size 12 but fit me size 6 & it fit me loosely not fitted so it would fit size 8 so I labeled medium. Button up crochet embroidery detailing & button back sleeves. Very good used condition! No stains, no holes, nothing to note! It's not sheer at all but it is gauzy feeling spring summer type material.
