Gaeltarra sweater 100% alpaca, size medium

Gaeltarra 100% Alpaca sweater. Size medium. Purchased, worn several times, but my eyes have become too sensitive for the material. Has yet to be washed and has only been worn several hours each wear. Always stored with care. Measurements: Laying the sweater flat, it is 21-22 from pit to armpit. From the top shoulder to hem it is 25". From the top of the roller collar to end of sleeve - 32".
