Purple polo long sleeve top

Purple polo long sleeve. Purple zip collar contrast side stitch long sleeve top. It has tiny fake paisley pocket flaps and the overall look is almost sporty but 70's? It doesn't have a tag but I would suggest for a small in women's. Bottom corner has BAJ embroidered very small. Must be the brand. Almost like a thermal material. Measures 17 inches wide by 17 inches long. I am 5'3 and usually wear a medium in women's for reference. Please compare measurements to your own to make sure it fits. Used item, has been washed.
