50s Style One Sided Slit Dress Style Ao Dai One Side Dan Garey ? Dan Garly? Cotton Print Egyptian Byzantine

A gorgeous cotton style print dress with detailed gold and pink designs on a beige background. it has one very long , hip-high, slit on the left side, where a metal zipper allows entrance to the dress. There are also a row of frogs along the left shoulder. Piping edges the arms, and side. Dress has been shortened, so you could let it down all the way...another 2 inches. It is a sexy form fitting dress, and I am trying to find out more about the designer. The only flaws are some hard to see ( probably coffee) stains in front. I bleached it, and also took it to the cleaners. I suspect the stains will disappear completely, with a few more cleanings. See circled close up. Go by measurements.
