Vintage 1960s Helen Whiting Black Wool/Blend Long-sleeve Dress with Tassel Belt

This is a beautiful vintage Helen Whiting black dress, most likely from the 1960s. The material feels like wool or a wool blend, and there is a partial liner. The satin, likely acetate, starts at the waist and goes halfway down to the bottom. The dress has normal signs of age and wear, especially on the seams. The piece has a matching belt with tassel ends. Overall, the dress is still in pretty great shape. There is no size tag, but the dress looks to be around a small-medium.
