Great for the price
Size: X-Small, Color: Pink
Great shirts for the price. I bought one blue, one pink. I guess it's the way of fashion now, though, but there aren't slits for collar strips to keep it straight, and most shirts I've seen are polyester with spandex. If you need spandex to wear a button down, you should get a larger size, please. Very comfortable, but the test will be Colorado summer with a with a white t underneath, but now very cool and airy.
