Vintage 1980s Dominique teal bright shiny robe kimono housecoat *missing belt*

It to pit roughly 19-20 inches, depending on how far open it’s worn. Belt is missing, but has the inner tie. Bright, shiny fabric that is semi sheer. Have seen this look as a kimono over street clothes, originally meant as a housecoat but feel it could be worn that way as well. Excellent vintage condition. Lovely purple piping details as well!
