TNA Grey Lambswool Zip Up Sweater

TNA brand from Aritzia 100% lambswool grey zip up sweater. Pre-worn and in good condition BUT there is a small hole on the back on the right side as shown in the 5th and 6th photo❗️I believe this is a size small however there is no size tag on it so please refer to the measurements provided for sizing❗️Measures approximately 16" ptp, 15" across the bottom hem, and 20" from armpit to hem of the arm.
