Vintage 50s Black Cocktail Party Dress by Rona Presents a Joan Doris fashion
35" bust, 26" waist, free hips, 41" long, neckline is 11" across, approx 16" shoulders - Model is 5'6"
Acetate material - has some stiffness and shine to it - not a casual material. Back metal zipper works great. No shoulder seams.
The dress is in nice condition - the only issue I note is the material shines in certain light, not sure if this is iron shine or just the nature of the material but have noticed this on similar party dresses.

This item is sold from an excellent, highly rated vintage boutique.
