This top came in one size and I ordered black. The top is oversized for me in terms of the sleeves but the length is perfect. The material is linen. To be honest, I had thought the material would be more on the softer side but it’s not. It’s not uncomfortable, but will wrinkle easily. The top is not sheer since it’s black. The material is also breathable so it can be worn in any season. Overall looks nice and can be dressed up or down.
