Princess Highway Perfectly On-Point Button-Up Blouse

Originally purchased from Modcloth. Rust colored blouse with cream dots. Listed sizing is Australian, like brand Princess Highway, but blouse runs large compared to their size chart. Armpit to armpit measure is 21 inches. Fabric does not provide stretch. It was an appropriate, loose fit when I had a 39” bust. In good used condition. Small snag on front, zoomed in photo included.
