Vintage 60s paisley blouse

A groovy, chic vintage paisley 3/4 sleeve blouse that buttons in the back and has a matching belt/neck piece with two size options. Feels like sateen. Two front darts and stylish side slits. Hip length. It belonged to an elegant woman with a Masters Degree in ancient art history.from Georgetown University. Designed by Lynn Stuart for Shirt Tree. Size 14 from the days when a 14 was not large! 27 inches long. Bust measures nearly 20 inches from seam to seam at the darts. I have no waist to speak of (29") so the is belt not a good option for me but blouse is glorious either way!
