Split-back button down

Condition: used, good, care tag has been removed. Info: Flowy sage colored button down with a split back, drop shoulders, and a functional front pocket. Armpit to armpit 21", top of shoulder to bottom hem approx 20". Story: Purchased at Forever 21. Cute top, but I've only worn it a few times. The last two pics show both the fit and my laziness in not getting the wrinkles out first. It does wrinkle easily and fits a bit short, including the sleeves imo.
