Vintage purple, raw silk cocktail dress

This is a stunning vintage raw silk cocktail dress. The maker is unknown as there are no tags present, but the style lines and fabric are stunning. It has a few flaws. There is some slight discoloration underneath the left under arm and right under arm. This piece is in need of cleaning. The tags have been removed so I do not know who the maker is. Measurements to come, but my guess would be a size 2-4. The dress has a straight neckline with very thin, spaghetti, straps, and incredible back, pleading detail.
