Sacoor Brothers Woman's Button Down Cotton Top 44

Unknown stains on backside at bottom. See last photo for both markings. I am not sure if they will come out. Would be hidden when top is tucked in. My client had this dry Clenaed. It is 100% cotton. (C) arm length 25" shoulder seam to seam 16" bust 38" waist 36" shoulder seam length down front 25.5" -- back 26.5"
