Dress it up or dress it down. This Michael Kors navy blue dress is made with a quality fabric that could be luxe on one hand but could be styled down for casual as well. Size XS. Fabric is stretchy, so could fit someone who is larger than XS if a tight fit is wanted. Slit on left leg side that is simple and modest but allows the skirt some movement and flare. Please see the 2nd close-up photo for the most accurate representation of the color.
