Red Silk Button Down Blouse

Vibrant red silk button up that I got in Japan. Fun but elegant pattern. See through -- looks so so SO cute with a black or red bra underneath. Marked size 11 and something (see last photo), but best fits a M. It's a bit snug around my chest area (for reference: I wear size 8 top, 36DD bra). Like new condition: no visible wears and still has all of its buttons.
