Vintage 60s Black Velvet Cocktail Dress from Ann & Lorrys Minto ND Dress Shop
No materials tag, this is a velvety material, it is not lined. Metal zipper down back. Sheer illusion at waist.
Approx modern size S/M : See measurements: 35" bust (17. 5" side to side across bust), 27" waist, 38" hip, 17" bodice length, 42" long - model is 5'10" US S/4 - dress fit as shown.
Good condition - the only flaw I note is super faint spots on the front chest area - see closeup where these are lightened - not obvious when worn.

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