I’m 5’11, 150lbs. I’m pretty tall and slender, and medium fits me on most brands. This shirt’s sleeves are short; they end at the wrist, which not the end of the world, but the worst part is the armpits. The shirt is weirdly tight around the armpits so if I raise my arms up it feels like the shoulder area is coming up too. Such a cute print, and cut, but just so weird fitting.
