The vibes of this light over jacket simply breathes Dorothy Zbornak from Golden Girls.  There is no label that lists size or the materials.  Based on the hand feel of the fabric this is a silk blend.  Primarily there is some sort of transparent and shiny plastic that runs through the weave to create a large plaid shape running through the green fabric.  Then the collar has a straw or again another type of shiny plastic running through the silk.  The label lists to dry clean only.  I used only a little water to try and spot clean a couple areas on the front.  Most of the small spots did lift with this, however there is still a lot of staining around the collar area.  I am feeling very hopeful that the bulk of this will remove at time of dry cleaning- but also a lot of this will not show during wearing.  Please review all photos for the sense of this discoloration.
