I loved this item very much, but it no longer fits, and I haven't worn it for the past two years. It's in good condition. There's no tag, but I believe it's 100% cotton. It's comfortable to wear. The fabric is slightly thick and sturdy. Size: Width (underarm to underarm) 40.5cm Shoulder width 36cm Length 54cm Sleeve length 51cm Please allow for slight variations due to amateur measurements.
