Michael Kors button down, XL, green, blue, white

Purchased at a garage sale. The sellers owned a dry-cleaning business and were selling the quality clothing that had never been picked up. This is in excellent condition. No tears, stains, pulls, or fraying. Appears to have always been dry cleaned. Colors are blue and green stripe on a white field. The size tags have been removed but it wears like an extra large. My mannequin is a medium, for reference. Chest: 24" across, length 34" (back of neck to back hem). Sleeve: 23" long.
