This is a lovely well preserved 1920s lace frock, meant to be worn over a shift or slip.
It appears as if this rare 1920s over dress has accent panels and edging of fine either bobbin lace or filet lace (I can’t discern- any help would be appreciated), and inner tatted lace panels on the bodice.
It slips over the head, and the neck and arms are small, so be careful if you wear this. Because this dress is so fine and fragile it is best suited for collectors. It has unnoticeable stains small holes, and comes as pictured, but without a slip.
