Vintage blouse

VGUC! This blouse is a piece of art! No flaws stunning feather🪶 prints. Small ones are colour hot pink the bigger ones are colour yellow, green, off white and black on a light aqua background! The fabric (not certain), I believe it is polyester! I already hand washed it in cold water! It is black buttons down! A pleat in the top back! High low! Size M
