Vintage Ms Sweetie grey blazer

Vintage (brand Ms Sweetie) multi pattern grey blazer. Single button closure. No fabric tags, but it feels like a thick wool (or wool blend) material. More of a Fall/Winter blazer. Size tag says size 9. My friend is a size 4 and it fit her great. Here are the measurements to be sure... measured flat (approx) bust 18.5, waist 17, length 24, sleeves 22
