Haider Ackermann's dress gives the illusion of a slip layered with a black top, but look closer and you'll notice the designer's mastery at work - it's made from precisely color-blocked panels of a fine knit and tonal-purple silk-satin. The midi skirt is cut on the bias, so it traces your figure and drapes fluidly. Wear it with statement earrings and sock boots for evening events.
