Really great party dress that is fitted bodice and cap sleeve, with a full skirt. On the front is a purple cotton sash-belt with two tones  of purple and two little bows for trim. The back waist is seamed with  self fabric piping. 
Under  the skirt is tulle stiffening skirt. 
I cannot find any flaws. This would be great for theater or movie as well as every day wearing. Still plenty of life in this dress.
I actually do not think  it was ever worn  before.
