One of a kind! New without tags. This sweater was purchased at an American Girl Employee sale and was a sample. No material tags or size but assuming no wool as it is not scratchy at all. Very unique! Has a compass button on the back. This would maybe fit a petite adult small? and youth XL?. Approximate measurements are: Pit to pit 18", Pit to cuff 14" and length from back of collar to hem 22".
