Vintage jet black lace blouse

This is a lovely jet black vintage lace blouse, can also be work as a very light jacket. In excellent condition, and I believe it’s truly vintage (please see the tag). Looks like a 50s style. Wide collar with a fabric bow. Plastic buttons down the front and on the cuffs. Lined, though it is sheer. No material tag. It’s definitely synthetic. Fashioned by Gregory. Marked Size 18. Measurements 40" Bust 20" Shoulder to Hem 19" Sleeves 16.5" Shoulder to Shoulder
