A vintage 1970s unbranded gown that is almost a perfect match to the other Gunne Sax dress I have on, but a smaller size.The model is a size 2-4 and this couldn't be zipped in back.
It looks like "The Exact Dress Worn by the Harp Player in 'The Love Witch'"
Details Include a Queen Anne Neckline with Raffia Style Ribbon Trim, A Tie Up Corset Detail on the Bodice, Large Bishop Sleeves with Elongated Zipped Cuffs, an Empire Waist, a Large Lace Panel Down the Front, and a Ruffled Hem
