I love this shirt. I’m a teacher and this shirt is part of our work uniform. It’s thick and structured which I love. The sleeves will be tight if you have any chub to your arm what-so-ever! I used to have scrawny arms and this shirt was never a problem. Gained weight over the summer and now the arms are snug. Washes like a dream (cold wash regular cycle and warm dry). Doesn’t stain. For reference I’m 5’4”, 135 lbs, 32DD and the medium fits perfect.
