This is a cotton-polyester sweater. It's a black sweater made of 83% cotton and 17% polyester. It looks undamaged and clean, but it has been worn before, so please refrain from purchasing if you are concerned. The size is 38. Measurements are taken flat: width 53 cm, length 58 cm, shoulder width (including the sleeves) 54 cm, and sleeve length 45 cm. These measurements are approximate. I'm selling it because it's been stored away. It has been dry cleaned.
