Vintage Joan Helpern Collection Woman's One Button Blazer in Size 6 Joan & David

This is from the Joan Helpern Collection This is the Joan from the famous footwear companty, "Joan & David". She started The Joan Helpern Collection in the mid 1990's so she could expand to clothing. This piece was bought in Italy. It is in great condition. Some of the pictures make this look like it's a gray color, but the first picture is closest to what it looks like which is black to me. I also feel like this runs a little big. Please check measurements. My approximate measurements: Shoulder to Shoulder: 16" Shoulder to Wrist: 23.5" Chest: 19" Waist: 17.75" Hem: 21" Arm Opening: 10.5" Front Length: 28.5" Back Length: 27"
