I'm selling this because I put it away without wearing it, and when I tried to wear it, my upper arms had gotten too big and it was too tight. It's a size L, but I recommend it for those with slender upper arms. Shoulder width: 39cm, Sleeve length: 40cm Body width: 45cm, Length: 79.5cm (Measurements are approximate and taken with the garment laid flat.) Please take a good look at the photos before purchasing.
