These look like they will be super loose, but after reading product reviews I decided to go true to my normal size (medium). I am a 5'4 female, about 140lbs athletic build. They are snug around the bust and upper chest (not uncomfortable, but form fitting), but loose on the stomach. In my opinion very true to color displayed. Have not tried washing them yet and may adjust my rating if they do not hold up to wash. Otherwise, I love the texture, love the material, color is exactly as advertised, and the fit is great for athletics. I run and lift weights, these are comfortable and breathable. I would also be inclined to pair with an over shirt and jeans and use as a casual outing shirt. Would recommend!
