Chanel Black Zipper T-Shirt-Sized Medium but Fits Small

Good overall condition. Zipper in front zips. Marked Medium but fits like a Small. No stains or holes but there is light wear on one side where purse bag hit and some dryer wear to the material to the touch. Am told by original owner that it is authentic. Priced accordingly. Length: 56cm Shoulder to shoulder: 38cm Armpit to armpit: 42cm Sleeve: 17.5cm Je parle français :)
