High-low Tunic with Zipper-back detail

Unique zipper detail, high low tunic from Wildflower in Yellow Springs, OH. I used to wear this to the office so I’d say it’s business casual appropriate or you could dress it up. I got it from a local store with their own brand. It’s a very nice, soft fabric. I don’t know what you’d call the sleeves, but they start lower on your arm, so it gives a mild bat-wing kind of look. The sleeves on me at about 3/4 length. Tag is worn, but it’s likely a women’s medium. I wear a size 8, or medium in most clothes. Shoulder area to front hem is about 26”, mid back to back bottom hem about 30”. Excellent, pre-owned condition. No defects noted. Smoke-free, Labrador-friendly home.
