Navy and black are so similar you can hardly tell them apart. Fit is exactly as shown - so be prepared for bra straps to show unless you wear strapless (also, they don't stay on a hanger - good thing they are slinky enough to be virtually wrinkle-free right out of the drawer). I like the drape in the dark colors I selected; but not sure if the seam running the circumference of the forearm would be attractive in lighter colors. Very comfortable to wear. Look nice with most anything. Can be dressed up or down with accessories (the right earrings are how I do it - diamonds, pearls, or fashion hoops).
