BCBG Paris, size medium. Excellent condition, it's practically like new. I don't know the material. I will guess polyester, but it has a softer silk feel to it. Sheer and see through. Has a striped up and down, vertical, pattern going on in the back ground. Army green in color. Starts to button down like a collared shirt, but then it doesn't: it is a pullover. Kind of a mock neckline, rounded, sits lower and not too high on neck. Nice long sleeves with buttons at the end. Can be worn cuffed or long. Works great tucked out or tucked in.
