This boa material has a considerable amount of stretch! Shoulder width: 46-47 cm Body width: 50-51 cm Length: 58-59 cm Sleeve length: 63-65 cm Purchased from a major brand recycle shop, authenticated as genuine. I've worn it at home and for short outings for over a year, so it has a certain degree of wear, but it's still wearable. Washed, brushed, and pilling removed. If you will take good care of it, please consider purchasing.
