Vintage La Fontaine Silk Blush Pink Blouse 80's Gold Metallic Thread Hong Kong 4

Vintage blush pink and metallic gold thread silk blouse by La Fontaine. I am not 100% sure of what era this blouse is from, but based off of the type of numerical sizing and the fact that it is made in Hong Kong, my best guess is it is from the 80's. Layered fabric detail where the fabric buttons at an angle underneath the collar, or be worn more open (pic 2). One small spot or fabric flaw on part of the collar (see pic 4). Bust across the front area measures approx. 19 inches.
