BOGO H&M mock neck sweater top

Lightweight sweater/long sleeve mock neck top from H&M in a gorgeous deep plum color. Condition: Fabric has some pilling throughout. Fits more like a small IMO, or may be better for a medium with narrow shoulders. It measures 14” pit to pit but has stretch. I’m 35-26-37 and it fits but is just a little bit awkwardly snug in the shoulders.
