I'm selling this item because the size didn't fit me, even though I purchased it here last month. According to the previous seller, it was worn a few times after being purchased last year, and I only tried it on. It's very light, so it seems like it can be worn as an outer layer or as an inner layer! Unisex design, size XS. Shoulder width: 45cm Chest: 47cm Length: 73cm Sleeve length: 60cm Please understand that this is a used item and has been stored at home.
