The actual size is larger than the listed size, and it fit me perfectly, and I usually wear a size 9. I've worn it about 3 times, but there's some color transfer on the inner lining from storage. The leather is sheepskin. The lining is 100% cotton (sleeves are 100% polyester). ・Size XS ・Length: 51cm ・Shoulder width: 36cm ・Sleeve length: 62cm ・Sleeve width: 14cm ・Cuff width: 11cm ・Body width: 37cm ・Hem width: 41cm
