Vintage 70s San Francisco Shirt Works Long Sleeve Button Down w/ Pointed Collar

Vintage 70s San Francisco Shirt Works Floral & Striped Print Long Sleeve Button Down Shirt with Pointed Collar No size tag. Based on measurements, I believe this is an XS. Measurements taken laying flat: Chest: 16“ Waist: 13.5“ Length: 24“ Material tag is too faded/washed to make anything out - it's blank There are so many amazing details to this piece - exaggerated pointed collar, ruched shoulders, harness style seamed waistband, & gorgeous vibrant flower print over a black & white striped background!!! The buttons end at the waist and then is open. There are not buttons missing. It was designed this way. I've never seen a piece quite like it & just love everything about it! Great preowned condition!
