Unused, only tried on. I believe I purchased it from a select shop. It's a bit thick, similar to knit fabric. The sleeves are puff sleeves and gathered, making it cute. It's a size L, but it runs small. There's no indication, but it might be for kids. I think it would fit an adult size S. ●Size (Please note, these are amateur measurements) Length: 44cm Width: 38cm Sleeve Length: 63cm Neck Circumference (laid flat): 16cm
