Lightweight (not very opaque) but just the thing for an extra layer under a white or sheer top. Length is good: it hits below the waist and stays tucked, but it's not too long. Despite a sort of slick feeling because of the synthetic blend, I would buy these again because they are holding up very well to washing (warm/delicate) and even in the dryer (on low): no pilling, and keeping their shape and stretch.
