Ribbed knit black long-sleeved wrap top. - Color: Black - Style: Wrap design - Sleeve Length: Long sleeve - Material: Ribbed knit I don't remember where it's from or where I bought it ( ;ᯅ; ) The string around the neck is for wearing around the neck! I don't know the size, but it fits perfectly on someone who is 160cm tall and weighs 45kg, so I'll say it's a size S!
