This is a knit sweater with different materials (see the third image). The sleeves are quite thin, like a blouse. The size isn't listed, but it can fit someone who usually wears a size L. Shoulder width: 35cm, Bust: 39cm, Length: 53cm. It has been worn several times and washed, so there is some slight pilling. Please be aware of this. Thank you for looking. 888775
