This is a vintage petite women's blazer made by Jones New York in a size 10P.
The blazer is black, white, and brown and measures about 20.25" from underarm to underarm, 21.25" from the top of the shoulder to the sleeve opening, and 25.5" from the back of the neck to the bottom hemline when laid flat.
The jacket is in pre-owned condition with a small tear in the back and is missing the tie closure.
