Purchased from an outlet shop over 5 years ago. I'm selling it because it's been sitting in my closet after being worn a few times. No lining. At the time, when I closed the front, I would wear leggings underneath, or I would leave it open and pair it with denim and a T-shirt. The waist is elastic and can be adjusted with the drawstring in the back. The sleeves are three-quarter length. Shipped via Yu-packet Post. Please comment if you would like to confirm the detailed size m(_ _)m
