Vintage Jack Winter Spring/Summer Blazer

Probably 1970s. This off white background with red and navy stripes blazer is adorable. It has a texture to it. probably a cotton poly blend. it doesn't look like true linen. it would look great with jeans, navy pants, red pants. there's no size in the jacket. it fits me perfectly and I would wear a six. but refer to the measurements. there is some padding in the shoulders but not much. this jacket is not lined. it has pockets. these measurements are approximate. measurements were done flat. sleeve: 23 in shoulder to shoulder : 15 in armpit to armpit: 18 in neck to base: 25.5 in
