Query: Great "Olga Style" nightdown

Olga style, at least that's what my wife calls it. Apparently, this style of nightgown was common several years ago, and was made popular by the Olga brand. She has surfed the net trying to find reasonable replacements, and first bought this style at a local Fred Meyer. After that, they stopped carrying it, and so she was thrilled to find these online. She's bought several, afraid that once again they will become scarce.
