POLO Ralph Lauren Alpaca wool blend sweater size small

Absolutely beautiful wool and alpaca blend sweater Super soft and cozy Off white color Neckline can be changed around depends what look you like It can be thrown over like a scarf or tied at the side I think sizing is incorrect. Pit to pit measures at 16” (I am size Small and it fits me perfectly) and length is 22 1/2”, therefore I am marking it under Small.
