Vintage 1950’s/60’s Kim Kory original dress

Vintage, one owner, cotton/linen blend with embroidery on 3/4 bell sleeves and bottom hem. Slight discoloration to the original white as shown in pic. Zipper closure down the back with hook and eye at neckline. Thin material so a slip would most likely be needed. No size tag. I’m estimating a size 8-10 based on other clothes from this particular owner. Open to questions and offers
