The pattern is Simplicity 4119, with half the skirt cut off. Also, I had to use three little darts in the bust because the fabric was too heavy to gather a double thickness. It left this huge bubble between the fabric and the lining that pulled the top out of shape. They apparently intended it to be made with something lighter.
Simplicity patterns 3956 and 4127 are true top patterns in similar style - but not quite the same.
