H&M Feminishm Definition Sweatshirt Pullover

This is a H&M Divided Feminism Sweatshirt. Has the word Feminism and definition. This is a reposh. I bought it thinking that it would fit a medium but was way too tight. Labeled as medium but for a typical sweatshirt look, how be better as a XS. Measurements: pit to pit 22”, neck to hem 22.5”, and sleeve 19”.
