Vintage flowered Satin blouse by "Kathryn" estimated size is 12

This lovely colorful blouse was inherited and likely from Hawaii. The brand tag says "Kathryn" and there is no size or Care Instructions. I'm estimating the size to be 12 and three quarter length sleeves. There is one flaw at the end of the sleeve and a few minutes with a sewing machine should be all that's needed to put this seam together again! It's really a beautiful blouse and is priced to sell!
