Love this style!
I am 5'5", 128 pounds and usually wear a medium top. This style fits just right... not snug and not too loose. It is surprising comfortable in the summer heat. If the temp is too hot, I wet the shirt a bit at the wrists, arms, wherever, and it cools me down and dries quickly. I LOVE not having to deal with applying body sunscreen!!!! Color in picture is accurate. This is my go-to summer top with my yoga capris or Nike shorts.
