This lightweight sweater is graded as OSFM (one-size-fits-most) and is knitted in Nylon/Cotton for super springy stretch-and-recovery in this sweater, making it an easy one to layer / fit many size gradations (likely Small - 3XL or so).
The whale graphic wraps around both sides of the sweater in an asymmetrical print that completes on the sleeve with a little tail! So cute!!
