The shirt didn't disappoint. I love the lightweight fabric now that it's almost summer in Texas. It is not see through either. Definitely a keeper. I plan on wearing to church so it's OK that it's plenty roomy. I’m 5’6, 152lbs and bought a Large. I think I might have been able to wear a medium if I wanted it a bit more form-fitting. Overall, I'm happy. I might buy another color in a medium.
