Beautiful Blueberry Colored Blouse Vintage Sz "14" Fits M/L

Hard to get true photo but color is most like 1st and 5th. Lightweight polyester. I love this blouse so much but sadly its too small for me in shoulder and has no stretch. Despite ptp, will probably fit M to small L best? PTP: 20" Length: 23" Back shoulder, between puffs 16" *approximate
