This blouse is gorgeous! The photos say it all. It does not have the fabric tag, but it is a polyester blend, feels silky soft. The sleeves are balloon at the bottom, with elasticized wrist. There is a keyhole opening in back, with a covered button. See photos for details. Dress up or down. Measured laying flat, pit to pit is 20”, shoulder to hem 24”. The blouse is in excellent, gently worn condition. No flaws. Coming from smoke and pet free home.
