Banana Republic Jersey Colorblock Dress/Coverup

What we have here is a lovely, dress up or dress down dress by banana republic. It is a black and royal blue color block in rayon and spandex jersey, very drapey and stretchy. Size S but stretchy enough to fit up to an L. This dress is cleverly designed so it can look great at the casual office, but can also be thrown on over a bathing suit. It's very comfy and is essentially new, having only been worn once. Perfect condition except that it's wrinkly!
