Purple Sequined Evening Gown, circa 1910 (possibly with later alterations) via eBay | Measurements: 32-26-n/a Irregular sequins gained popularity around 1905. The style and outer materials all look authentic, circa 1910 or so, but the dress may have had a few alterations over the years (it looks like someone fiddled with the sleeves). Perhaps it was re-worked c.1930-40 or as a costume piece for theater? From the seller: "Part of a museum deaccession." (dress is displayed backwards)
If the colors used for the hand-tinting reflect those of the original gown, then this woman was making a statement that she wanted the right to vote! Purple symbolized dignity, white purity, and green hope.
1800-1905 dresses kill me... I have several different show tunes in my head for this one, like Down Once More/Final Lain or The Wedding. Vintage dresses, "Go! Go now and LEAVE ME!" because I want all of them.
